The Xorg devs have literally stated as much themselves.
The vast majority of those commits are literally because of Xwayland.

HDR literally can't be added to Xorg without rewriting the entire stack. They've been trying to get HDR working for something like around 10yrs before they gave up completely.
Wayland on the other hand has been designed from the ground up to be completely expandable, directly addressing the largest problem with Xorg, maintainability.
Yes, that's true. What would reduce edge cases however, is if you reported those bugs.
That day is coming sooner then later.
That's fine, however you should switch as soon as it becomes viable to do so.
