OK. My two cents.
First, a disclaimer: I fully respect anyone's opinion on this list.
Now, my opinion. I personally keep getting good results wuth 5000K / 2.2
gamma, and lately L*-based gamma (but don't ask me about it yet). Yes, I
work in cave, practically. So, I may not me representative of a lot of
people's situations. But it's working great for me and *I* happen to have
found all kinds of good conceptual (scientific?) reasons to stick with it.
Using a Eizo CG21 monitor (looking forward to the CG220) with a 10 bit LUT,
*I* can't see any visual banding in my images in Photoshop.

For starters, let's not forget the reality that 16 bit scanning may not be
full 16 bit. It could be 12 or 14 expanded or re-encoded in 16 bit,
depending on the scanner. Secondly, Photoshop's own "16 bit" mode is nothing
more than 12 bit in disguise. Still, 12 bit is quite honorable. Now, I like
to think of the world as comprising the reality as what we see it today but
also as comprising the reality as what we'll be seeing in the future. So,
for all intents and purposes, it may not make any difference on a printing
press but, given the choice, I would not want to commit my masterpieces to
only 8 bit. For tonal edits, in particular, 8 bit is criminal negligence.
