"submodule.fetch-branches" suggests to me that you're thinking of submodule branches that track the remotes of the submodule. The proposed UX is more about how we have submodule branches that work in tandem with superproject branches. A user who is only concerned about a single submodule can cd and make their changes as if the submodule were a standalone repo - I think that's pretty well-supported. The missing link being able to coordinate this work with the superproject. >> > What I could see as a possible improvement is to add the branch ref to the >> submodule ref file - not replacing the commit but adding to it.

I would not like to depend on a developer making the call each time a clone occurred. I'm sad to admit that I don't really know where to start on this enhancement, though, even if approved. Agreed with regards to both points, i.e. using a config instead of CLI option, and not knowing where to start..
