What's ultimately underrepresented are people with small hands, PERIOD.
As if it's fine that men with small hands can't compete (very common too btw), but oh-boy, since it's especially affects women, now it's a super big wrong that has to be corrected.
No, it's wrong on a more fundamental level - there's no good reason to exclude small handed people at all from reaching the highest level, regardless of sex or anything in between.
