No.
Is the answer. Including everything only makes WotC's coffers richer.
Not including things is what makes your game richer.
I think I agree. WotC's goal is to provide as much saleable information to adapt to the widest variety of games. Including everything can be downright silly in many situations you can set up adventures/game worlds in. It can also be unnecessarily draining to the pocketbook, depending on your financial situation, when th emain goal is simply to play a game one enjoys.
Back to OP question: They're here, whether I like them or not (personally, I don't). I prefer Genasi and Deva characters from the "new" races so that's what I play when I go that route. Those are simply the options I happen to like (except the spikey, crystaline "hair").
