That was easier than I expected.

The downside is that it doesn't automatically catch the problem if the
notification observer moves to another class, but at least someone will have to
delete it in that case, and might notice that they ought to test manually in the
new place.

I don't understand what you mean by "moving the notification observer to another
class", but the change lgtm.
