You are right. I was thinking about minimal change to
submodules which would allow user selectively checkout them
but the most minimal one is just selectively run `submodule
update`. I think in scope of this feature no changes to
git-submodule is required.

Yes, but they still are only somewhat ahead of some stable
branch. And not very much, if you count space: _All_ git
development, with whatever unstable branches, takes 5-10
times less space than its carved in stone history under
`master`.
