The nice thing about the proposed method is that the hub does not need to verify the request. Since it's a reply to a ping that the hub sent, then the hub knows for sure where it came from and can safely remove that subscriber from the list without verification.
And, yes, sending an unsubscribe request is not hard. But I bet that, for many subscribers, since it's not a show stopper, it'll probably be at the end of the todo list because it can always be done "later" and because it's so easy to simply ignore pings you don't care about.
