I think it's a bit premature to do that. At present, the subscribers have been written to expecting editions, and the messages they emit are quite generic, e.g. `"published"`. If you had a, say `OrganisationPublisher` that emitted a `"published"` message, then we'd either have to rewrite all the listeners to handle multiple types of things, or rename the messages they emit. Either way, everything will get more complicated. I'd much rather defer that until this "some point" arrives. ;)
