Right.  But I'm still worried about .git/modules/$name.  Can you
explain why it's a better idea than having a dedicated ~/bare?  In the
case when I have it in ~/bare, I can do many more interesting things:
for instance, if I cloned a repository that is actually another
project's submodule for instance, I don't have to re-clone it when I
clone that superproject.  What's more?  I can remove submodules and
attach a worktree to my ~/bare/repo.git and use it as a separate
repository easily.  I can move submodules between projects.  In
comparison, .git/modules/$name just seems like a mess.

Well, I'm against the change in principle because add operates on
worktree paths, not URLs.  I don't want to change that arbitrarily.
