This is meant for MUC presence. Servers don't necessarily track muc joins
or other directed presences.

The hint in the xep is meant for clients that might support this (sending
directed presence after receiving a pep node update) but servers that
don't. So there might be code in the client sending this but it should be
wrapped by a check if the server will support it. If that makes sense...
