I followed the pattern used for attidentity. But why will it spit out 
warnings? It doesn't ask for the missing stuff from an older version.

Incidentally, I just checked this by applying the patch and then running 
through the buildfarm's cross version upgrade check. All was kosher. 
Upgrade from all live branches to the patched master went without a hitch.
