> Wayland is now as old as Xorg was when wayland started because X11 is "old and crufty" and still not usable.

How is this comparison supposed to make any sense? When Xorg started it was a fork of the existing XFree86 codebase (due to XFree86 changing license to one not deemed open source compatible), not starting from a clean sheet of paper. And XFree86 in turn wasn't a clean sheet implementation of the X protocols either, it IIRC started as a bunch of patches on top of the reference X11 codebase which goes back to the 1980'ies.
