But if we have notmuch as a cache of the tags, then don't we already
know the tree objects that need updating?  Yes, we would probably need
some consistency checks for when things don't work as planned, but in
the common case we ought to always know.

Perhaps I'm misunderstanding these tree objects, and you're suggesting
that we don't even tell notmuch about them.
