When a type (or it's properties) are marked [obsolete] the designer should surface those as designer compile warnings as well.

Yes, this would help a lot...
I 100% agree with Laurent

This would help raise the designer's intelligence, great idea.

Useful for frameworks and toolkits that want to evolve smoothly without breaking their user's UI!
