We use a true/false preference so we can tell the difference between
disabling the watch vs never having the watch. This is so we can toggle
off and on the preferences for a container (like the bucket) without
losing any bubble-specific preferences.
Previously when an item was `created`, we'd track the event, update the
summary text, and broadcast the notifications. But now that we have a
draft state, we shold do all of this when it's published instead.
