redman, I think you're mistaken. I just installed 12.04 in a virtual machine, and here's what update-notifier did:
When there were no updates, it showed no icon.
When there were basic updates, it showed an orange icon.
When there were security updates, it showed a red icon.
This matches my memory of how it worked.
It's also worth pointing out that my patch simply restores code that was already present in older versions of update-notifier, so it's pretty unlikely that it behaves much differently.
