I've installed GUIX in VB in order to test it. I've noticed that GUIX does offer EXWM as WM. Very nice btw!
However, now EXWM has a maintainer issue. I wonder why the GUIX Team does not take the lead here?
To me that's the best way to fix the EXWM maintainer issue.
Any thoughts/discussion on that regard?
To learn more, see System Crafters bringing some light about the EXWM situation
Also, I might go discuss that in the GUIX IRC (If I find the time)
