I have to admit I was surprised, and not in a pleasant way.  When I started
playing with Guix, I went over the etc/git/gitconfig and copied the parts I
liked into the .git/config.  For some reason I do not like tools automatically
touching the .git directory, and now I have the include there (5 times).

I think turning it into a manual step, with the granularity proposed above, is a
good and welcomed solution.  At least in my opinion.

Have a nice day,
