It's not like no one at the #PSF knew this either. I raised it with @nedbat on IRC a few years ago. He even raised it as an issue in the CC issue tracker on #GitHub at that time. Coraline Ehmke closed the ticket citing, IIRC, "biological essentialism" as the reason for doing so.
Still, that didn't stop the PSF adopting the CC with the #Drupal Diversity Statement mod, so they're just as complicit.

Finally, before circling back, this last part is not directed at anyone explicitly tagged anywhere in this thread, but to people who come across it later (which is likely with all the hashtags used and the thread should be seen and boosted): I have a hard line, zero tolerance for interphobia. I will block and report interphobes and I will refute interphobic bullshit (at least sometimes).
Though if you read this far, that should be obvious.
