We might want to recommend entities use XEP-0184 (Message Receipts) if
they want to ensure their messages are delivered (or at least be aware
that they haven't been delivered).
If so then perhaps XEP-0155 needs a new field that enables clients to
agree whether or not they will use message receipts throughout a session.
