Well, nothing in XEP-0045 as it stands today forbids or discourages the
sending of groupchat messages with <subject/> elements within the
conversation flow, and <subject/> is not reserved for use in MUC rooms
only to advertise the room subject. So IMHO if a client assumes that any
message with a <body/> and <subject/> received in the context of a MUC
room pertains to the room subject, then it is making a false assumption.
But in my experience, a lot of clients don't show <subject/> even in
messages of type 'normal' or 'chat', let alone 'groupchat'. And the
thread handling we're talking about here is not mainly predicated on
handling of <subject/> anyway (it's mostly based on <thread/>.
