fwiw, for x11 side of things, I had previously made some patches to
push yuv buffers to xserver via an extension to dri2 proto:

I've not had time to work on this for a while, so the patches may be a
bit dusty, but maybe a good time to resurrect this.

looks like your changes are mainly intended for wayland, but I suppose
there should be some way to make this work in x11 as well, to keep
things more similar looking for the stuff on top of the winsys
backend..
