I don't think it is broken. Leaving the .git directory inside the
submodule makes perfect sense for some users (e.g. those which never
intend to push their submodule somewhere else) and doesn't do any
harm unless you want to remove it again in the future (or need to go
back to an older commit where the submodule directory would be in
the way). We have to think very hard before making such changes to
behavior quite some people may rely on, even though I agree some use
cases would profit from it and I think we would do it differently if
we could start over again.

What I think we need rather soonish is "git submodule to-gitfile",
which would help your case too. We should then hint that in those
cases where we refuse to remove a submodule when using "git rm" or
"git submodule deinit" (or the "git mv" for submodules I'm currently

Hmm, it does a clone first and then adds the submodule and the change
to .gitmodules, so I still believe "add" is the correct term for it.
So I really like the color the shed currently has ;-)

I won't object such a change (even though I suspect it'll turn out
more complicated than that).

How did you come to that conclusion? Nested submodules make perfect
sense and most people agree that in hindsight --recursive should have
been the default, but again we can't simply change that now.

Not that I know of.
