Well, I agree this fix would allow non-compliant implementations to
keep misusing wl_surface.commit, and that could potentially remove any
motivation to find an appropriate resolution for the bug below.
I'm fine with deferring this patch, but I still think applications
should not start setting EGL surfaces up before they have been set up
by the compositor.
