> You cite some programs that didn't properly keep their data in a single dotdir, and use that as a reason why a single dotdir was bad?!

No. It's literally the other way around. It's bad that they keep everything in a single dotdir, because now I have to poke through dozens of folders to see where they hide their caches and other bloated garbage that shouldn't be backed up or kept in git, and where between all that garbage they're hiding their config files.

If all caches go to ~/.cache, I can exclude them all with a single setting, and I can put all my configurations in git/backups by adding ~/.config.

Same as with /var/tmp vs /etc vs /var/lib; if I want everything thrown together into a single folder I can just go use Windows.
