The use case is covered:
"The 'from' attribute SHOULD be the full JID of the original sender in
non-anonymous rooms, but MUST NOT be in semi-anonymous rooms (where
the 'from' attribute SHOULD be set to the JID of the room itself)." -
So, the information is available. Most clients don't display it
though. Sending unavailable presence for unavailable participants with
messages in history may cause some clients to display leave messages
including JIDs, but that's a hack.
