This code was committed to master in https://github.com/pfsense/pfsense/pull/1421/files
and was backported to RELENG_2_2 on 28 Jan 2015 - https://github.com/pfsense/pfsense/commit/7c7c2ba2f0ac0789bbc52af93f715dee10d329af
So it is not that new.
In master, etc/inc/notices.inc still has the necessary code.
I guess the code for usr/local/www/system_advanced_notifications.php was just forgotten in bootstrap integration.
