Previously, the events could be expected to be sent (or sent) in strict
accordance with supported_events.

Now, you are essentially sending out-of-band events, because the
receiver requested supported_events -- but is getting much more than that!

You broke a fundamental assumption of the interface -- that
supported_events accurately and fully represented all events sent via
the new API.
