I see. That's fine for tolerating protocol failure. Now, the persistence
is not only for the purpose of reliable protocol only, but also for the
purpose of status query. If I said I support status query, it will be
unreasonable for me to delete the persistence, since the spec doesn't
indicate a deadline which I can delete the persistence after that..
Am I on the right track?
