The applications panel show notification controls for applications not doing notifications
Using g-c-c 3.31.90 on current Ubuntu, the applications panel seems to list every single .desktop installed on the system and show a 'notification' switch for each of those, even those not doing notifcations (gnome-calculator, yelp, ...), shouldn't that be the case only for those using X-GNOME-Autostart-Notify=true?
