Pretty please? Nobody on earth thinks 8bpp is a reasonable default
anymore. Should I just assume I have carte blanche to push trivial
things like this? I'm happy to have literally anybody revert anything I
push that causes problems if we go that route.

For that matter, I'm happy to have pretty much anybody pushing code if
they're confident in it, with the same "anybody can revert too" caveat.
