Not quite the place to ask about this (this thread is just about chaotic-AUR) . Would be better suited being posted in the Garuda Community or under the Request section.

Anyways, getting to your question… That Depends on the desktop environment when this will happen. (some already have it standard). KDE 6 will have Wayland by default next year, so I’m guessing Garuda will eventually with its KDE offering.
