Accept & Do Not Send a Response

Yes absolutely! In fact, I was certain that it already worked this way and it has caused a lot of confusion within our organization. My expectation is that the response would be recorded (and properly tracked) but the organizer would not receive an email notification. I see almost no legitimate use cases where the attendee would have a need to have their response not tracked (if that's the case then... just don't respond). If such a case does exist, it would be the rare exception rather than the rule.
