Terminology here is a killer.
The long/slow stuff is measured in lab by lactate levels, and has indicators normal people can use: stay below 70% max heart rate, be able to talk conversationally while exercising, etc. If you work up to it you can row at this pace for 90 mins or 2 hours and your HR and splits will stay constant (no drift). This is called zone 1 of a 3 zone model. This is zone 1 or 2 of a 5 zone model. It's what I mean by long/slow.
Threshold is a workout level harder than long/slow. Your lactate levels rise, but stabilize. You can row steady state with constant (but elevated) lactate. Normal people indicators -- your HR is 70-90% of max on long pieces. You can't talk in sentences. Longer intervals can be done at this level as can long pieces. Marathons are run in this zone. If asked, you'd say "that was a hard workout". This is zone 2 of a three zone model. Zone 3 or 4 in a 5 zone model.
The next zone up lactate keeps rising, no steady state. It's still aerobic. This is short, hard intervals. Race level 2Ks are in this zone. Pieces done at this level have to be short - the rising lactate levels eventually force you to shut down. This is zone 3 of a 3 zone, zone 5 of a 5 zone.
"slightly faster than anaerobic threshold pace" would be flat out sprint with less than 20-30 seconds duration that started after at least a 4 minute rest period. It uses a different energy system than is mainly used during a rowing 2K, but does have training value. Max 30 seconds on, 90 seconds off are maybe in this bucket, but I lump them in the previous.
Originally some training schemes said training in threshold <zone 2 of 3 zone model> or <zones 3 and 4 of a 5 zone model> was "bad", counterproductive. They said avoid it. Later research showed it wasn't bad. So now best practice (per some exercise scientists) is to do a mix of long/slow and hard workouts, where the hard workout can be in threshold or higher zone.
I appreciate the detailed response and clarification. I know there are many models out there and plans with science / studies to support them; it seems like it then comes down to a bit of an intangible, being buy-in - finding some kind of model or plan you believe in and will commit to. I hope I'm not fully discrediting the lower intensity work as something that can work or provide value, rather I am just questioning how much value it provides when training time is more limited or capped.

essentially control intensity more through stroke rate than anything?
Yes, that's how rowing is done. Quality, not quantity. We can worry about anything we like, even HRR, but if the stroke is not pulled with good technique, we go nowhere and may risk injury.
Sums are very simple. If you want a 300W 2k, train a 10W stroke (eg rate 20, 200W) then use it at rate 30.
Are we training too easy?
If below 2W/kg at aerobic ratings (<24), yes.
Very good points and not necessarily something I have thought too much about. My "aerobic" work tends to be a bit above 2w/kg but I would still like to improve that further. A lot of my aerobic work hovers in the low to mid 9W stroke range; when I rated up a bit yesterday for faster intervals, it dropped to just below 9W stroke. More power and speed on the whole but less efficient or power per stroke. This is something I can certainly focus on moving forward.

As I always understood it, it was Zone 3 (of the 5 Zone system) that they thought you should avoid as it was more tiring/taxing than Zone 2, but didn't bring any additional benefits when compared to Zone 2. Zone 4 and 5 are also more tiring, but do create any additional benefits when compared to Zone 2. Issue with this from my personal experience is that mentally Zone 3 is much more rewarding, so the physical toll to pay may be worth the mental stimulus to keep me going again.
But that is just my interpretation.
I never quite understood why so many people avoid the "grey zone" or zone 3 training if more limited on time. I also never understoof why so many people avoid it if training for longer aerobic events like a HM or FM, esp the latter, as the race is in that area for quite a bit of it.

In all of my many sessions over 20 odd years, I've never done a session where I could hold a conversation. To me, it's just another signal for people to take it "easy"
I think modality can be a factor in the talk test as well. I tend to find that I can talk in close to if not complete sentences in the high 140's if running; with rowing, its a bit more strained at the same HR.

100% Hard sessions is better than no sessions. By a lot.
The low/slow stuff came from looking at how the most successful athletes trained (vs. coming up with a theory and finding data to prove it). Once published, when people tried long/slow they got faster and the people who didn't use it became less competitive, so the bulk of athletes shifted. Nothing works for everyone. Mike Caviston has been hugely successful without rest days and without low load training. Seiler has been pretty successful with his long/slow stuff. He's in his 60s with a cycling FTP above 350 watts, his daughter won bronze in the Tokyo Olympics women's marathon.
The long/slow claim is there are body adaptations that happen at low load that will not happen at higher load. The current speed skate world record holder works out 30 hours/week at low load. You'd think a speed skater would focus on higher output - and they do for part of their training. But the 30 hours/week is at conversational level.
One surprising stat is that marathon runners who mainly work out below marathon pace are faster in the marathon than runners who spend more time at marathon pace or higher.
NCAA limits coaches to 20 hours/week of coached workouts. Most elite college rowing teams use all of it.
This also goes back to the main point I was attempting to get at.
If I had 10-12 hours per week (or more) to commit and focus on training, I would likely take a different approach than what I am planning. The limiter for me ends up being time.
I can commit consistently a solid 6 hours a week, not 12, 20, 30+. I am fortunate that I can commit to 6 hours per week consistently as a lot of folks aren't willing or able to put that much time in.
With those 6 hours, I know I need to be intentional to get the most out of them, and knowing that the aerobic system needs attention for a good 2k, it comes back to the most effective way to train that system given the time constraint.
