the notification service is deprecated (as is code in options/).  why are we
adding more uses of it?

As discussed offline: The CL fixes some useless firings of that very same

apparently the tests had depended on just that to work.  To fix the tests, I've
re-added the notification there.  I'll look whether I can find a better approach
later.
