Yes, that is very useful.

Since subtrees are really just directories in a single-history
repository, a subtree pull does "prommote" the changes to the
superproject because there is no superproject/subproject.  That's one of
the reasons subtree can be used to create subprojects out of existing
repositories.

Subtrees and submodules really are very different models.  I see
advantages and dsadvantages to both depending on one's work flow.

That would be great.  Do you want to start work on that?  I can
contribute some text about git-subtree.
