Well, I think you'd find that given nobody implements message
receipts anyway, it might be suggested that method has complexity
issues all of its very own. An increasing number of clients already
support ping, so adding that in seems like a lightweight way of
increasing reliability for critical messages.
My point is to ack everything just like in SIP.
Weren't you just complaining about additional traffic overhead?
XMPP is pretty reliable anyway. There's really no need to worry about
the vast majority of messages, just as we don't bother using MDN in
email most of the time.
