There is a rush because Red Hat isn't interested in maintaining wayland anymore. Neither red hat nor Kde/gnome are interested in supporting x org in the long run. For wayland to get better and do the things it currently lacks at it needs a greater user base and that's why there is a rush by major people in the linux community (kde and fedora for example). Right now its at that there are somethings that wayland can't do that x org can and somethings that x org can do but wayland can't. Since wayland is being developed actively and is the future it's the obvious choice and x org has far more annoying use cases that are just not gonna get fixed "unlike wayland". Majority of the users shouldn't have any problems switching to wayland.
