I have developed a few small softwares. Unfortunately, I'm trying to graduate
software development. I want to stick to software tinkering. I just want to
write a few tiny scripts here and there, and I don't know much about emacs lisp.
I don't know the intention behind package-vc.el, but I think it should be
flexible enough to keep commit depth at 1 during installation and updates.
That's not difficult if you know some git commands. Gentoo linux keeps commit
depth at 1 for all package repositories by default.
When people use package-vc.el, in many cases, they have to use it because the
desired packages aren't available on emacs package repositories. janet-ts-mode
is one example. I just want the latest commit from VCS packages that are not
available on emacs package repositories.
If no one wants to make package-vc.el flexible enough to do that, I guess I
will just stick to elpaca.
