    calendar: Copy Source from MessageTray
    
    The new notification system will still use the concept of notification
    sources, but heavily deemphasized and not as the primary entry point
    of the notification system. Therefore it is much easier to put the new
    system in place and move over once it's done than to modify the existing
    code gradually without breaking consumers.
