I added the repos to my existing arch install sometime last year I think. It’s pretty seamless in that regard, I think I only ran into a mirror sync issue once, and it was resolved a few hours later.

My CPU supports the v4 packages, but I’m not really sure how much benefit there is for most things. (And things like tf/torch aren’t coming from the repos anyways.)

I also use their kernel. I can feel a difference between stock and zen or stock and cachyos, but I don’t think I’d be able to tell zen and cachyos apart tbh.

I definitely wouldn’t switch distros for it, but since it’s a trivial, drop in repo, I’ll keep using it.

Adding another organization isn’t ideal trust-wise of course.

Regarding the second point: applications change it. It’s really annoying. I think Discord and Zoom both do it.
