I don't believe sex stereotypes, what you call "gender roles", should ever be codified in any sort of official paper, no more than the party people vote for or the religion they follow. However, the sex of an individual who is born without any sort of ambiguity is useful data in a lot of cases, medical of course, and social to determine who has access to what segregated sex facility and so on and so forth.
