Nobody is forcing you to use Wayland. Nobody is arguing that X.org's server will disappear from the face of the earth.
Actually, that's exactly one of the major reasons put forth for switching to Wayland. The very comment you replied to quotes it:
>>> a major maintainer of X server telling you he's not going to work to maintain the project anymore
If the project ends up truly unmaintained, it really would end up disappearing from the face of the earth as the platform under it (the hardware, the kernel, etc.) changes to the point that it becomes non-functional.
I’ve seen this happen multiple times with replacement systems: as long as people can escape back to the old system the new one remains rough around the edges, but once the old one is turned off the new system rapidly improves to production level quality.
The problem is that they can't be fixed, as I understand. People are asking for things that some see as features and others see as bugs.
The only way to keep everyone happy is for both to continue co-existing, but unless something changes, it doesn't seem like that's going to happen.
The kernel has a pretty strong backwards-compatibility stance, so you'd need to wait a long time.
Nobody stops you from running an outdated and insecure distribution to use X11 (in this hypothetical future). Nobody stops you from patching X11 to support newer interfaces.
If you want to stick with X11, you can. Nobody urges you to upgrade.
You don't want people to use a new thing because it might siphon off resource you're benefitting from now?
If you love X, go work on it, or pay people to. Otherwise... what possible point are you trying to make?
Did I express any want in my comment? I didn't even say anything about my preferences. I wonder if perhaps you replied to the wrong comment?
> what possible point are you trying to make?
To correct emersion about Wayland being an option. Do you think what I said was incorrect?
No, sorry. X11 clients are eternal, there's just way too many of them out there that are line-of-business and will never be ported to anything else. So I'm always going to need some solution to make those apps work, and since for the foreseeable future that probably means "run a nested X server that translates things to the native display server's API", that means Xwayland isn't going away any time soon, and if/when it does it'll be replaced by some other translation layer I'll need to support.
