Extensions may need to monitor such occurrences for various purposes, so it stands to reason that there should be some notification of them. Surely if we have a 'compose-from-changed' we can have a 'compose-message-changed' event, right? One could think of such an event which complements keypresses or such an event which is triggered both when a key is pressed and when the message changes otherwise.
