Of course, because it didn't even reach beta quality yet and there are no packages outside of some testing branches.Not a single person actually uses Wayback to do anything.
But their software being unfinished and unusable, never stopped troons from advertising it.
And even if it would have a stable release, there isn't a reason why anyone would run it, as long as xorg exists.
The purpose of wayback is to offer an answer to all the people who will come asking:
Once they officially admit that xorg is discontinued.I am using this desktop environment with this x11 window manager or compositor, what should i do?
And it is a deliberately bad solution. A stripped down wayland compositor that runs XWayland to then run a x11 compositor.
People who follow their advice and use it, will have a buggy broken environment and will be asked to "upgrade" to native wayland when they complain.
