My point was pretty much that I care only marginally about that
argument. Nevertheless, I'm not all that convinced that Wine even has
a lot of OS X users. If it does, that's certainly not reflected in the
number of active developers (Perhaps if you count people that are paid
to work on Wine on OS X things look better there, but I think few of
those run OS X as their primary platform by choice.) or the number of
bug reports we receive from OS X users.

So it should be easy to convince Apple to implement EXT_texture_snorm,
right? I don't think it's unreasonable to require some features from
the underlying OS when you want certain features to work in Wine. It
certainly works like that for the BSDs and OpenSolaris, and probably
would for e.g. Haiku if they wanted to run Wine as well. I don't see
why OS X should be different.

Yeah well, hacking something together is easy. Doing it properly you
should also be able to blit to those formats, render to them (you can
render to e.g. Q8W8V8U8 even in d3d9, d3d10 can render to all kinds of
formats), read them back, and probably do clears on them. If we had no
other choice that would simply be a pain, but pretty much all the
linux drivers support either the various NV_texture_shader extensions
