If you're writing a bash package it'd probably be preferable to package for this rather than per-distro. By making it easier for maintainers, you get more packages - so maybe this is a good thing?

As a user, I keep my dotfiles in git. Having something like bpkg could help my dotfiles "just-work" across more platforms, so maybe it's a good thing?

I'm not particularly compelled either, just pointing out how it might be useful.
