I would like to see a similar project that fixes Wayland. Like, can someone vibe-code window positioning, add SSD to GNOME (damage was already done, but still), and add the ability to send events so you can automate and drive the app offscreen for testing.

OMG, yes, please, get rid of all those composers, all that mess that people are doing. X11 is 40 years of battle testing. Wayland in 22 years (it already has 18) will be 100x worse than X11.

A Dockbar I am working on https://github.com/edumucelli/docking/ is a pain to build on Wayland. It already supports a lot of composers and even mutter/gnome with that Gnome shell extension, but at what cost ...

One of the issues with Wayland is that it forces every compositor to reimplement the X server, badly.

So you can't really "fix it", short of patching e. g. Gnome's compositor, with patches that will never be accepted upstream.
