I forget another similar problem if SXE uses a MUC chat room. Some
MUC implementations send a short history to newcomers. Even if the
contact is online, the newcomers should not get from the past, when
they were not in the membership session. I don't know whether XEP-0079
can be used in this case.

Also, which servers currently implement transient messages from
XEP-0079? It is not mandatory in XMPP Core and XEP-0228 says it only
requires XMPP Core (section 2.2) if I understand the section correctly.

I would be interested to follow discussions about shared edition.
