I'm not sure about that. The way that Ubuntu does the notification is Update 
Manager monitors http://changelogs.ubuntu.com/meta-release-lts[1] or _http://
changelogs.ubuntu.com/meta-release_ depending on whether or not /etc/update-
manager/release-upgrades has been set to "Prompt=lts" or "Prompt=normal" 
respectively. This can be set via the frontend software-properties[-qt]. So, unless this 
can be converted to AppStream metadata, I'm not sure this is completely useful, nor 
am I sure the team would be willing to implement something there.
