I'm going to presume the lack of response that this means there are no
plans to support Stanza Ack-ing. A pity since this makes mobile XMPP
clients far less trustworthy in terms of knowing that the recipient
*actually* has received the message.

I've updated https://support.process-one.net/browse/EJAB-532 should
anyone else see this as an important feature.
