I agree and use Arch as well, but of course I wouldn’t recommend it for everyone. For me, having the same distribution on both server and desktop makes it easier to maintain. I run almost everything using containers on the server and install minimal packages, minimizing my upgrade risk. I haven’t had an issue yet, but if I did I have btrfs snapshots and backups to resolve.
For this reason, I use kebab case for directories. But because I agree underscores show spaces better, I use snake case for files.
