Having already taken a look at this during the sprint, I must say this
is an elegant solution that provides an answer to a few long-standing
issues of groupchats:

- It can be used to provide fully anonymous chatrooms (as in: even
  owners cannot see JIDs, but does not hinder moderation and other admin
- It greatly simplifies the state tracking of user identity for things
  such as message corrections (and now, reactions) in semi-anonymous

If this gets enough traction, I hope we can have this occupant-id
accepted in other places such as setting affiliations an so on.
