This is why I think it's better to treat warning messages as just messages and not validity levels

IMO the only thing that it's clear enough along all this discussion is that warnings are a can of worms (and IMO bad practices). Everyone has a different viewpoint of what they are and what they mean. This is why I'm not in favour of providing "direct support" by sub-classing and prefer a "this is just a special kind of text message" approach.

 CI.
