Beyond the above mentioned tacit admissions, didn't nearly every major active dev on the xorg team state explicitly via various emails, blog posts, and conference talks that they saw no reasonable way forward as a matter of tech when it came to the now 21 year old xorg source, now 34 year old XFree86 source, and 41+ year old protocol model that is X11?
All that said, I wish the best of luck to the X11Libre team on their endeavors.
