Yes, but you have an event id that serves as the handle, rather than an `a` tag. Replies would tag the update event, which tags the create event. Since the updates don't replace the create, the create is still accessible, so you can pull all events, or just events for a given revision. No data is being deleted, so clients don't have to guess. Right now, replies that only tag the `e` tag of a given revision get lost when the post is updated.
