The fact is, in no other fields you would have people thinking about doing this. It is just that they do not care. It is not part of the culture to focus on women from a sexual/stalking point of view.
They only care about lack of women in management and engineering positions and the salary difference. Or how to better manage the maternity leaves in the company to keep interesting jobs for the women while potentially working only 80% while have small kids.
I will note purely that CPAN has quite a lot of similar modules categorizing authors by several attributes, most notably country of origin. From that perspective, it's very easy to believe the author acted entirely in good faith and from a non-creepy perspective, without having to invoke the idea that it's some kind of sexual/stalking thing.
You are forgetting one thing: If any given situation can be seen two or more ways, there are people that will naturally see it in the worst possible way. It is no different when it comes to people really determined to find examples of The Man crushing all women.
