In worst case Asterisk has terminated unexpectedly (or "core restart now" is used) and we don't have a chance to do this. I would like the experience for the user to be that Asterisk comes back and they are subscribed, persistence achieves this in both the best and worst case scenarios.
Well, yes. Agree.

Remember the hook we have so that we terminate subscriptions for extensions that was deleted when the dialplan was reloaded.

You can not terminate a registration from the server. If you do support SUBSCRIBE for registration states you can do a bit more messaging to the UA, which would be a good thing to support, especially since you want to support multiple registrations per account.
