Expected Response When Polling After Stream Delete

[independentid]

If a transmitter polling stream is "deleted" before the receiving entity "shuts down", it is unclear what should happen at the polling endpoint. How graceful should the shut down be?

Note: I see notation that Paused or Disabled event should send a Stream-updated-event upong being re-enable, but no mention is made of sending event when changing state to pause or disabled.

If a stream is disabled or deleted it would be useful for a period of time for the polling endpoint to indicate in the polling response that the Stream is disabled or deleted (e.g. include status response attributes). This allows the poller to download remaining events, detect the change and exit gracefully.

Eventually after all events are gone, specify status 404 is to be returned. Or specify status 410 Gone to indicate the stream has been removed (though the url was valid).
