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). And the people who want Xorg support maintained in perpetuity rarely seem interested in maintaining Xorg themselves, at least not properly (see this history of Xlibre introducing bugs and LLM slop).

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