Yeah along the lines of that, but one thing to keep in mind:

We already have --rebase and --merge which do slightly different things
(I think). Adding --pull here should behave similar to them. Like fetch
and merge is the same to pull without submodules.

If I am understanding your goal correctly your --pull would be
different. On the other hand: A --pull makes no sense if we apply it to
the existing --merge option since it merges the recorded sha1 into the
current HEAD. Just a fetch would not really make a difference.

Thinking along the existing options I would probably still expect --pull
to merge something into the current HEAD. So maybe we have to iron out
where this command/option should go. But changing that once we have a
patch to discuss should not be that much work. So please proceed with
--pull and once we know exactly what it does we can polish that.

Until now we have always called this workflow floating submodules. I
imaging since the submodule floats to the newest revision (whatever the
user chooses that to be) instead of staying at the recorded sha1.

"tracking submodules" sounds strange to me since the term tracked in git
is mainly used in combination with exact recorded history (e.g. tracking
branch). Since it is about *not* checking out the recorded sha1 but
something that can change I think that could cause confusion.

I think floating is a more unambiguous term and already known on the
