Yes, I know. The sending application (or middleware) still has to tell
the sending MSH the conversation's status. However the receiving
application (or middleware) does not need to tell the receiving MSH the
conversation's status, if we add the status attribute to ConversationId
element. Because the status information is propagated to receiving MSH
automatically.

Exactly. However we can reduce possibility of application's bug by
better design of lower layer middleware such as MSH. In your idea, both
sending and receiving application have to tell its MSH the
conversation's status. But in my idea, receiving application does not
need to do it. Thus possibility of receiving application's bug is
reduced. I think it is better design.
