Actually most of repos you linked have the last activity of months ago. It's pretty worrying though.
Wayland is just a protocol.
Look at the work on actual compositors, like mutter and wlroots to see some activity https://github.com/GNOME/mutter https://github.com/swaywm/wlroots
Why do you say Wayland is abandonware? The last activity in the repo is from a week ago https://gitlab.freedesktop.org/wayland
