How does this work when you are a toplevel developer and do not
have the submodule cloned and checked out?

Our code should treat having the submodule directory and not
having it when there is a mode 160000 entry in the index equally
likely.  Cloning and checking-out is _not_ the norm (nor the
exception).

When submodule is not cheched out, it is never modified.

How so?  Can't you update the index alone?
