Right - true "read" receipts are impossible. 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.

 Dave.
