ftr been meaning to do a new snapshot for this to see what still needs fixing, but it's often left in a transitional semi-unusable WIP state at runtime (segfaults easily, changes break some important features that need to be re-implemented but aren't yet, etc...) and no longer been able to find a commit where it "mostly works".

Tried again with latest (from last commit in Sep 2022) but was met with a segfault just trying to change keybindings a few seconds in.

Think this may be difficult to support until there's a new finished release, tried to save it before (I used to use this years ago, don't anymore) but I wouldn't see a problem with last rites at this point.

As for clang support, from
