Wayland is a replacement for X11 in the same way that a tricycle is a replacement for a tractor.
They have thrown everything difficult out of the spec and only implemented the most trivial functionality around a security model which you must actively break to get actual work (like screen shots) done.
That Wayland is 10 years old and still barely usable should tell you how far software developers have fallen in the last 30 years.
Now look at population growth. The Roman empires population was largely stagnant between the 1st century AD to the 3rd. Africa's population has increased 10 fold in the same period.
Africa does not have a 50% child mortality rate. What it has is an an average of 5 children born per woman. In short: not even the worst place in Africa today is as bad as the best place any time before 1900.
And color calibration.
>such as different HiDPI across multiple monitors
I had this working with multiple X11 servers 20 years ago.
>And that has changed in the past 2 years
I was told that exact same line 5 years ago. I guess it will be just as true in 5 years again.
