Ok, I thought you were going to publicize the option, if it goes away in the future, then I agree with you here. I also can't think of a reason to use the check. Is there any reason not to remove the flag now? :)

We also check for type compatibility between the explicitly-specified result type and the type associated with the context of the method (e.g., the class if it's in an interface/category/class extension/implementation/category implementation). It's a bit more work than I'd like to do in the AST itself.
Ok! Thanks Doug,
