Yes, especially since X11 code isn't badly written. It gives me the feeling X devs were fed up with a huge codebase and wanted to write something new and shiny, albeit with 10% of features, pushing the maintenance burden downstream. The Wayland evangelists touting it as desktop-ready and no-true-scottsman'ing any critique also smells fishy. What Wayland did bring was more fragmentation.

And yes, their attitude toward missing features is the same as GNOME's: WONTFIX parade 24/7.
