I don't get the issue with "maintaining Xorg". Like, I get that it has a "cost", I just don't understand why that cost would be an issue since it's basically fixed, marginal cost (and has been since like 2015): the software is already mature, so it's unlikely to see relevant changes, or even minor changes (if that's what we want to mean with "dead"). That means, it can be affixed to a specific toolkit and environment to build (if this isn't being done already - which any mature project like RedHat should be!) basically guaranteeing it'll build forever. You can just set a virtual button or a yearly crontab to do it. Fixed, marginal cost.
Contrasted to that, what Wayland is doing is kinda a representation of the worst ways of capitalism: centralize the profits, socialize the costs and the externalities (redesign, recode, rebuild), and blame society (the Linux communities) for it, all for a variable cost that is unbounded in time and space because you never know what's gonna cost a small project like a text editor to reimplement the entire desktop stack "just" for Wayland.
