Yeah, sorry, I didn't give all the details on why this RFC patch, my bad.
Basically, in downstream RH bug 1289714 , Robert Mader (cc'ed) is running some proof of concept to see how he can improve the support for older games in Xwayland.
So this patch here is mostly a follow-up on my comment 15 in that bug , where I was arguing that Xwayland should not add fake modes by itself but use whatever the Wayland compositor advertises.

No, I don't plan to let users change the modes via xrandr, but from bug 1289714 it seems that listing available modes helps some games (not sure why, I don't play games), even though input transformation is broken.
There is a lot more for this, this patch here is just a first (small) step (thus the RFC) to use the available modes listed by the Wayland compositor rather than faking arbitrary modes in Xwayland, and since I didn't reckon this patch would break anything, I posted that to the ML for more feedback.
