While outliers exist, this has to do with averages. On average men are taller than women, and this difference usually manifests between the ages of 12-15. This confers an advantage. However, for trans athletes who transition before puberty it's far less cut and dry and there's a good case to be made for inclusion.

My understanding is that's true for muscle mass. However, if they transition after puberty like Lia Thomas did, height and wingspan will remain; both of which confer huge advantages in swimming. Apparently that's a major reason why Michael Phelps did so well, his arm span is ridiculous.

I'm sick of the concept it represents.
