The >= stuff makes this harder to parse than it should be IMO.
I'd just list each modifier explicitly.

ditto. At first I couldn't even spot the difference between this and
the C8 case.

Any modifier will do for these formats.

I'd also like to see .format_mod_supported() + modifiers[] for
cursors as well. Those should only accept LINEAR+ARGB8888.
Apart from those issues, I think this is looking pretty good.
