But receipts are generally about moving responsibility; hence XEP-0198 acks move it to the next hop, XEP-0184 moves it to the client, and a read receipt spec would move it to the user with an explicit ack. I suspect there's actually little practical advantage to most people above a simple response of "OK", but in military and other critical environments it could well be useful, since then a client, or server, can see messages have been acknowledged - or have been missed.
