Could you please extend the description of your use-case so we can
understand your goal better?

The following questions directly pop into my mind:

 - What means the maintainer does not track the submodules sha1? Does
   that mean the superproject always refers to submodule commits using
   branches?
 - What happens if you want to go back to an earlier revision? Lets say
   a tagged release? How is ensured that you get the correct revision in
   the submodules?
 - In which situations does the developer or maintainer switch between
   your attached/detached mode?
 - What is the "repository branch" which is given to the developer by
   the maintainer used for? Who creates this branch and who merges into
   it?
 - What are these subsequent "merge" or "rebase" update operations? Do
   you mean everyone has submodule.name.update configured to merge or
   rebase?

Still puzzled.
