If you allow an override, then I don't see how having the initial
information in the tree is any better.
When new information gets in from the tree, you're going to ignore it anyway.

What happens if the URL changes?
You have to modify .gitmodules in _every_ branch you have?

What if someone is working on his own branch of the superproject
that needs some changes in his own subproject?
He needs to modify .gitmodules, but when the changes go upstream,
this .gitmodules changes get merged as well.
Now imagine several developers doing this.
You end up continually having to modify .gitmodules.
