I'd rather we waited until wayland sessions are feature equivalent with X.
Sweeping this under the carpet and then not providing users any way to get to something that
works on their hardware. The Fedora world isn't just an Intel laptop.
We know off enough bugs in mutter/wayland and feature differences without
forcing it on the world. Maybe we should spend more time fixing the deficiencies
we know about before going out and finding new ones.

For examples this change deliberately breaks optimus machines in
rawhide and stops USB monitor hotplugging from working, these are features
I spent a lot of time making sure they worked in Fedora and you have just
removed them without consulting me. As such I request you revert this.

Also I'd wait until mutter stops requiring Xwayland running for native apps.

Dave.
