Disproportionate to how rare perhaps, but not disproportionate to how loud.
Furthermore I’d argue rarity is not really an argument here. A new doping could also initially be rare; it would still provide an unfair advantage.
Anecdotal evidence also is meaningless. I might lose a sprinting race to a trained woman, but that doesn’t mean male sprinters aren’t inherently better than female sprinters. They obviously and clearly are.
In any case, I’d personally have no issue with this in friendly matches. Also I think olympically speaking this would be a perfect case for the paralympics, who have experience with (arbitrarily) adjusting competitions for varying levels of bodily differences.
