Winjab originally had support for multiple conversations with multiple
resources, which is not what you're suggesting, but it's not what the current
I-D says either. The "users" I heard from (in droves via private email) were
_real_ honest-to-god users using my client. They all (and I mean ALL) wanted the
behavior that the draft is suggesting. It doesn't ever make sense to have
multiple chat windows open to the same bare jid (user at host) since that is not
how we converse in real life. This approach is basically the opposite of what
you're proposing. The current I-D proposes a middle ground.

This stuff has come from experience of the jabber community (client writers
mostly). Not from a "marketing droid" survey of some kind.

"Following the client" is a LOT harder than this one scenario. The model that I
use in Exodus is this:
- When a user dbl-clicks a contact in the roster, open a chat window and send
the first message to user at host. This allows the server (and possibly filtering
rules setup by the recipient) to determine which resource to send the message
- When I receive a reply back, I "lock in" that resource (user at host/foo).
- If user at host/foo goes offline, then I unlock the window and start sending
messages to user at host again.
- If the user sends me a reply from a different resource, I lock in that new
[.. and here is the kicker ..]
- If I _close_ my window, and dbl-click the same contact, I reopen the same
window (showing old messages), but reset the jid back to user at host.

What typically happens in the situation you describe above is that when you go
away, I would _usually_ (but not always) close the window. Which resets the JID
back to user at host. This is how the majority my users seem to operate (based on
feature requests/bug reports/private email, etc..).
