I'm not concerned that you didn't research this change well enough, I
just find it a bit iffy to introduce semantics in git around FS
operations that don't conform with that of POSIX & the underlying OS. My
*nix system happily accepts an "rm -rf" or an "rmdir" of the directory
I'm in, I'd expect git to do the same.

Isn't this the same, conceptually, as trying to remove the root
directory, but from a Git perspective?

i.e. Something along the lines of
https://superuser.com/questions/542978/is-it-possible-to-remove-the-root-directory
(their answer is 'no' without a special option, default since 2006)

If I read the arguments correctly, Elijah is saying that Git shouldn't
delete it's own root (cwd) directory, and that it is already implicit
within the current Git code.

I do not think it is about protecting "root"; the series wants

    cd t/ && git rm -r ../t

to leave an empty directory at 't/', because "git rm" was started in
that directory.
