Essentially, he does not want to use "git rebase" and have a way to
disable the command on a branch that stg is actively munging.  And that
is something git proper can help with the user, which is why I earlier
referred him to pre-rebase hook.

As you suggested, however, git proper should not know the internals of
Porcelains, so I'd rather not to have that logic deep in git-rebase
itself.  But the pre-rebase hook shoud be the appropriate place for the
user to actually populate with stg specific logic ("is stg set to
actively munge this branch") and activate it for his repository.
