Mine are, but that’s because I’ve published my .dotfiles for everyone to use. What I haven’t done is made them usable by anyone who isn’t using my dotfiles. That wouldn’t be that hard to do, I just need time to develop infrastructure around it (which is probably worth doing anyway because my dotfiles are feeling a bit creaky).

EDIT: Scratch that. I just saw that git-config supports include directives. The infrastructure is already done for me. Now I just need to separate that bit of code out of the main dotfile repository.

Pairing git-config's include directives with a separate semver-tagged repo for your Git code sounds reasonable.

I guess what I was getting at here is that I haven't come across a good analog to npm for shell scripts or dotfiles "modules". Using node/ruby/py/etc instead of shell scripts is often overkill (debatable for gitgoodies), but having the standardized infrastructure is valuable.
