I am not sure if hiding changes to the recorded SHA1 from the user is such a useful thing. In the first step I would like it if it was kept simple and only the submodule update machinery learned to follow a branch. If that results in local changes that should be shown. The user is still in charge of recording the updated SHA1 in his commit. >From what I have heard of projects using this: They usually still have something that records the SHA1s on a regular basis. Thinking further, why not record them in git? We could add an option to update which creates such a commit. Since git is all about changes I am hesitant to hide them from the user. > I'll replace -r/--record with --follow-branch in v4. Sounds good.
