I could see people wanting to use this to add simple chat rooms to existing products. I would probably think about going through the XEP-0045 standard to verify that you are satisfying all the requirements for XMPP Chatrooms (if you aren't, you're probably pretty close), and adding that to the documentation. If someone at an actual company were to try to use this, it would be helpful if they could say that hermes supports the proper XMPP standard.
