alt Hacker NewsFor what conceivable reason would you want to recreate the male and female division using a dozen or more proxies for sex instead of just using sex, to wind up with people being placed into the same buckets they would have been if you just went by sex in the first place? This seems ideologically motivated.
The controversy in these comments answers that question nicely. It seems likely that such a change would obviate these edge cases, though they may introduce their own; that seems worthy of consideration.
Really, the question seems better turned around: why use a known bad proxy for physical ability when another one might be better?
