My main objection with the the error instead of the warning is, that by 
making it an error, you are implicitly shoving 'final' into Objective-C 
through the backdoor.

@interface Foo
{
    char final[];  // can't subclass anymore :P
}
@end


I am perfectly fine with the non-fragile/ARC part of Objective-C going 
hogwild, with whatever they want to do. I am obviously unhappy, if 
that's to the detriment of non-fragile. I don't really think that's 
"dictating" though. :)

Ciao
