Several Linux distributions for embedded deployment, ChromeOS and WSL 2 (in the near future), Fedora, Ubuntu, all make use of Wayland
What's the function of the X.org maintainers now? Mainly merging drivers. It's been like this for over a decade, heck back in the old days several bold moves were made for network transparent 3D acceleration with X.org including working patches but it was never realized.
With everybody else going their own way, it might be time to revisit and reinvigorate these efforts.
X.org doesn't really have maintainers, ever since Adam Jackson stepped away as release manager a few years ago. Alan Coopers it merges security patches, but most device driver support is handled in the lower levels now.
note that Alan Coopersmith is paid by Oracle to work on Solaris.
This is the core criticism that's been advanced since a decade ago. X is the standard, it's an actual standard. Wayland is apparently both a protocol which is defined by an XML file, a reference implementation, but yet not a standard. It's going to be tough to get it into deployment until it is standardized and finished, so to speak.
It also doesn't give me any benefits, the programs I use all use X so Wayland becomes a parent process to X and that's apparently its job. Why not just skip it? X is very time worn and honed to a sharp edge, it can run on incredibly minimal hardware. Wayland depends on a lot more.
