Absolutely-it's important to consider the selective environment that a trait evolved in and evaluate all possible tradeoffs. You can see this in certain fishes where pharyngeal jaws permit eating hard prey (new food source!) but also increase the processing time for soft prey (bad if you're competing against critters that eat faster). Beaks are good for some reasons and teeth for others.
