Redhat stands to lose their defacto control over X after the XLibre fork so they have to stop trying to kill it. Who would have thought that competition would make things better for everyone?

Alan Coopersmith works at Oracle, on Solaris. I don't know of any effort to use Wayland on Solaris, so maintaining X really is their only option.

OTOH, RedHat seems happy to let X die.

I doubt they care too much. They probably just have customers with applications stuck on a legacy window system. And they pay for that maintenance.
