If it *didn't* do that, the storage space from the old tree would
continue
to be taken up over time unless you took explicit action.

We could add an option to keep it though?  I'll admit that some of
these choices in the command line tooling are a bit arbitrary - the
underlying library and model is extremely flexible though.

Right.

At the moment, we're actually in a model where updates are
initiated manually.  A feature of doing automatic updates would
be a good place to also implement this behavior of automatically
tracking the latest.

(If we *do* have multiple branches, then an interesting question
 arises as to how the client learns about new releases)
