It's a bit tricky: in Messenger, messages are called messages. If you're using Messenger as an event bus, you can of course call them events. I'm mostly using the word "message" to keep consistent with messenger (and not confuse with the EventDispatcher), though I keep "event" wording in the code examples.

This code block didn't seem relevant anymore. I think it originally came from whendispatch_after_current_bus was not going to be included as a default middleware, so you needed to show how it was added to config.
