Bodily functions are already blacklisted.
Opinions:
If calories per day is ever put in, it should be tied to a “size” stat, not gender. Characters are working, moving, and fighting outdoors all day; the differing caloric needs of sedentary males and females are going to be irrelevant.
Warmth from beards, hair, etc, is something I’d fully embrace, especially if there’s an option to put your hair up or take it down to change how much it warms you and whether or not it warms your face as well as your head. Still, it’s essentially fluff; a little bit of head and face warmth are trivial to get and not strictly beneficial in the first place.
Aside from “women don’t grow beards,” and pure fluff elements like what your underwear and career are called, I don’t think anything should differentiate women and men in cata.
