I’ve just tested your series, I wrote a small part of it long ago but
never finished it, nor tested it anywhere else than on my setup, so big
thanks for that. :)

I have found a small bug though, on both Wayland and GBM platforms
there is no 2101010 EGLConfig without depth+stencil, wasting a full
buffer for applications which don’t need it, such as Weston.

There is also no 2101010 GLX configuration exposed on Xwayland
according to glxinfo, not sure if it’s an oversight or if you plan to
fix that in a latter series.

I also tested the Sway compositor, it has completely messed up colours,
but given the discussion about gnome-shell you may want to just ignore
it here, I’ll report a bug upstream.

I don’t own any fancy hardware and couldn’t see a difference on an
allegedly 10-bit screen (edid-decode says “10 bits per primary color
channel” about it, but with my eyes I couldn’t see any difference on a
test 16-bit PNG with mpv), but otherwise your series seems to work
properly!

Thanks,
