If Wayland is the future, then the future was 12 years ago. Since it hasn't really caught on or solved the same problems that X.Org accomplished a long time ago, it seems kind of pointless to continue pursuing it at this point. In my opinion, the best thing about X.Org is that it's no longer changing. I remember installing updates for X.Org all the time and booting to a black screen on multiple occasions.
The issue is trying to implement a radical change in the userspace Linux ecosystem. It's not possible without a ton of effort, so it takes an incredible amount of time, sweat and tears. That's the reason it takes 12 years and counting.
The utopian philosophy of "Linux is about choice" has doomed any idea of a Linux desktop.
