I agree.

I think the EGL_MESA_screen_surface extension we've been drafting on the
dri-egl list is a pretty good approach (and if anyone disagrees, it's
still open for discussion :). It might make sense to design the mode
setting library API concurrently with that to make sure they're a good
match.

As you mentioned MLdc in your talk, I took a quick look at the OpenML
1.0 spec. It seems to me like MLdc is overkill in some areas yet doesn't
provide everything we need in others (in particular, it's not obvious to
me how it would allow binding outputs to arbitrary surfaces).
