I agree to a certain point. Those feats that are basicly racial cultural do not carry over (just like a Techno-Mage human should not be able to take nationalty feats).
But those feats that are more biological should be allowed. For example, their is a feat that allows a Centarui to control his tenticles. This is more physical and should be allowed as it has nothing really to do with culture.
This goes hand in hand with how I think that if a person (no matter what race) was born, grew up and lived on a planet housing a different race then he should be allowed to take cetain cultural racial feats. What makes a feat cultural and not biological is of course up to the GM.
