its not just at the room level, its at the org level. the standard practice is that people create rooms in a slack org - and they are guaranteed that they are private to the org. one more step is where i can create private rooms to a few people within the org.

The protocol doesnt have an issue - but the people building products on top of XMPP have an inherent distaste for organizational workflows.
