We've had a request for adding the option to have security classifications on Iris plots (OFFICAL, OFFICIAL-SENSITIVE, etc) in a way that is somewhat controlled and consistent.
We believe this could be possible as an optional parameter when creating a plot, but it wouldn't be realistic to automatically have it added due to external users. (In other words, you'd have to specify if you want a classification on your plot).
We think this should only be a small or medium effort issue to add, (days rather than weeks).
