You're probably right, it was a bad example.  The point is, unregistering and
shutting down are two distinct activities and mtypes are supposed to have
a clear meaning.  No doubt people will write apps that infer something has
shut down simply because it unregisters, but that isn't always true.

I claim app.event.shutdown has a clear and distinct meaning apart from the
unregister mtype, it serves an administrative function, and does no harm.
So, feeling more strongly about now as I apparently do, please leave it in.
