While a lot of men do like playing female characters (and vice-versa) and the lack of a penalty for playing one encourages this, the point of how women respond to sexism is not at all moot. It's a very real factor, and women gamers are a huge and growing market, and it would be very foolish to alienate them for no good reason at all, and no attempted justification other than a supposed commitment to realism.
I remember playing under those rules in the Old Days. We had two female players in our group who were not at all amused with the modifiers and argued that it didn't really do anything to balance the game, and counter-argued about Constitution modifiers and the like. It was well out of my interest at 12-15 back then but it resulted in our GM removing the caps on abilities as well as Racial Limits as well, after he decided it didn't do anything for the game.
30 years later and I still agree with him -- those limits didn't make the game more fun or interesting and just upset people.
