I chose my words carefully, I said "drop vesa" not "drop Xorg". It
means F37 will not have a vesa driver for the Xorg server to use. Xorg
will still be there for at least another release, probably several.

It's likely that the long term plan for preserving X11-only desktop
environments would be to run (say) weston such that its only client is
a fullscreen Xwayland, rather than Xorg driving the hardware directly.

Yes.
