I'm not offended. And I agree that often you want to pursue
communication (either one-to-one or many-to-many) after receiving an
alert. So send alerts to a chatroom or specifying the chatroom where
discussion can happen is important. I think we can handle the latter
case with a 'replyroom' header in the pubsub notification (but we don't
have any examples of that in XEP-0060 yet).
