apparmor profile ships 'local' override file, but doesn't #include it in the system profile

The package-installed apparmor profile included with telepathy-mission-control-5 (/etc/apparmor/usr.lib.telepathy) doesn't #include the local additions/override file (/etc/apparmor/local/usr.lib.telepathy), which does however exist. This means a user will have to modify a non-configuration file to make any policy changes. The documentation in /etc/apparmor/local/README indicates this should be avoided, leading me to believe the non-local files in /etc/apparmor are not protected as 'configuration' files by dpkg)

In a default install, the apport profiles for dhclient, firefox, cupsd, ntpd, and tcpdump all #include their respective local overrides, so this appears to be expected behaviour and definition of a profile.
