That's probably more a case of laziness by the spec writers than a
real requirement for anything that's in there. I suppose there's
MESA_texture_signed_rgba for hardware that couldn't possibly support
either of those extensions.

We wouldn't demand support, signed textures simply aren't going to be
supported if the underlying GL implementation doesn't support them.
Sounds reasonable enough to me.
