Sort of. That's why you think about things before you allow them - that means that less things have to be taken away again. And it's about the kind of players you have: The guys I play with have no problem with powers being edited out if they turn out to be too powerful.
I have found that those who throw a fit because some power-boosting ability is taken from them because it broke the game are usually power-gamers of the bad sort, the ones who try to win the game over the others. Might not always be so, but the cases I witnessed were like that. Those who complained about nerfings were usually those who tried to make the best possible character. At times like that, I don't mind certain people leaving the table - I might be the one sending them away.
Remember: I don't say that you should allow overpowered stuff. If something's too powerful, weaken it. They can play the half-dragon, but the str and con bonuses are each 2 lower. That sort of thing.
