Xorg isn't neglected for "ideological reasons", it's neglected because development is work - and most of the people with knowledge of the problem domain decided they didn't want to work on Xorg anymore, and most of the companies that were paying for it decided they didn't want to pay for it anymore (apart from baseline maintenance, Xwayland and security fixes).

You're free to spend your own time and resources doing the work, but you don't get to dictate how other people spend theirs.
