There is also the fact I like lights that can kick out more oomph that a
Dynamo can do, and I’m not wild on such cut off beams, while my commute
light has a low wide beam on low, ie fine around town and so on, with the
High Beam to give a bit more punch in the woods and so on.

 In my experience, a modern, StVZO-conforming LED based headlight is more
than good enough for riding in city traffic. More power usually only
serves to blind other cyclists and still can't compete with car
headlights. Riding in the woods and in the dark, on the other hand, is
better done using a weaker, but wider beam.
 The only reasonable need I see for more powerful headlights is when
driving on unlit rural roads. Here you need a powerful low beam and
sometimes also a high beam.

I agree woods riding is different than road riding. But I've done lots of unlit road riding with dyno lights and no problems. So have countless randonneurs.
Night vision varies, I'm sure; but I believe the general desire for more and more and more lumens is caused by the same mechanism the triggers the desire for more and more rear cogs, less and less bike weight, bigger and bigger pickup trucks, etc. After a while, people are chasing advertising copy or quickly diminishing returns.
