It doesn't hurt (on the contrary) to aim for gender neutrality. Although, I do agree that we have to accept that it is impossible.
Children do go through a phase of defining their gender identity, and seem to feel the need to find a way of distinguish themselves from the opposite sex while asserting that they belong to their. It can't be avoided, I don't think. It does become a problem when one is seen to be superior to the other, or children are forced into those roles, with no option for overlap.
As then later they go through a phase of detaching from their parents and starting to get attracted to the opposite sex, which they derided just a few years before. 
As an example, DS has grown with all kinds of toys. OK, not Barbies, but then I never found them particularly appealing either. He chose his toys, or they were given by relatives and at parties.
They included lots of cars, balls, some construction (he's not very fond), a kitchen, a vacuum cleaner, a baby and crib, some crafts, etc.
Curiously, when my niece comes by she goes to play with the "girl" toys that we have. And that belong to DS. :) Some of which were also a favourite of another cousin.
The point is that they were available, as far as possible we didn't assign value to none of the toys, but we were happy for him to play with what he wanted, and never pushed any particular type, although wheels and balls were always his favourites.
I'm quite happy with this type of "gender neutrality".
But, perhaps more importantly, he sees me do things that fathers do too. And he saw his dad do things that could be more commonly done by mothers.
Regardless of his preferences in clothes or activities, I'll just be happy if DS doesn't see himself superior to or worth ore than women in any way, and if he doesn't feel that he can't do something because it's a female thing.
How other parents go about it, if the end result is the same, great.
And as fashions go, trying to be gender neutral can only be a good thing, rather than bad. :)
