A narrower follow-up, since the general answer is now clear:

Whether anyone has held at a sub-maximal dose long term and kept the result, or whether the maintenance data only exists at 2.4mg?

I will push back on the "any working dose is fine" framing. The maintenance evidence sits overwhelmingly at the top studied dose, and the extension data shows regain tracking dose reduction rather than tracking stopping. Holding low is reasonable; pretending it is evidentially equivalent is not.

All true, with one condition: that curve is for people who reached the dose on schedule. Anyone who slowed the ladder for tolerability is on a different, flatter curve, and comparing yourself with the published mean will make you feel like a non-responder when you are not.

Genuinely useful, thank you. I had the facts and not the framework. Sending this to two other people who asked me the same thing last week.

From the other side of the consultation, briefly. There is a difference between no evidence and evidence of no effect, and this subject is one where the two get swapped freely in both directions.
