Objective-C has added things, but it has largely not changed existing things. As I said in another comment, languages generally do not change — they just accrete.
If you feel like a language is missing something, that might be fixable — but if you feel like a language either added the wrong thing or did something the wrong way (which is the OP's concern), that is a much more difficult problem, because after release you can't take away what's already there without making people angry.
