I think it would be more like:
(1) $EDIT ~/.gitconfig-super
(2) git config --global \
includeIf.gitdir:/path/to/super.path .gitconfig-super
I know that is probably a bit more cumbersome to figure out than
treating the super/sub relationship in a special way. But I suspect for
a lot of cases that it actually ends up even better, because the
situation is more like:
(1) $EDIT ~/.gitconfig-work
(2) git config --global includeIf.gitdir:~/work.path .gitconfig-work
and then it covers all of your projects in ~/work, whether they are
super-projects, submodules, or regular repos.

Yeah, I think it is worth mentioning in "gitmodules", and probably in
git-config where we define per-repo config.
It may also be worth calling it out especially for url.insteadOf, just
because it is not clear there when the URL rewriting happens (it's not
insane to think that it happens in the super-project, that just doesn't
happen to be how it's implemented).
