That makes it relevant for stories like "I met him at a bar and we shared a few drinks," but not "I sold her a cup of coffee this morning" or "She's interviewing for our team."

Gender is also kind of a useless differentiator in many contexts because of the way that gender correlates with behavior: if there's a group of mothers or Catholic priests or even schoolteachers or venture capitalists, I'm much more likely to find pronouns for short/tall useful than for male/female in communicating about specific members of that group.
