That's not the germane point. There are applications dating back over 30 years written for X11. Thousands upon thousands of them. Compatibility matters. Wayland may turn out to be a flash in the pan. Those applications aren't going away. I have many open source and proprietary applications which I fully intend to carry on using. They don't, and won't, support Wayland. Unless you're using a modern toolkit which will be modified to support Wayland, you're not going to be using Wayland in a hurry. Because you'll be tied into the X11 world.
