We should probably leave it up to the UA to decide whether to use a key per origin, or per Service Worker, or per push registration (or some other heuristic). The spec can then simply tell authors to make no presumptions about key re-use (i.e. authors should expect to have to store a separate key for every push registration, even if in some cases these may be the same).
