Xwayland is basically Xorg but with a different backend. Xwayland will 
be absolutely fine for the testing purposes. In other words, X11 != Xorg.

Well, it also depends on what desktop environments are up to. Based on 
my discussions with GNOME developers, it seems to me like they are set 
to moving forward with Wayland+Xwayland. With my KDE hat, that's about 
the same what we want to do too. We would like to have a robust 
foundation such as Xorg that works reliably and doesn't cause us issues 
so we can focus on improving Wayland.

Obviously, GNOME and KDE are not the only fish in the sea but it's worth 
keeping in mind what their plans are.
