Trans women have competed as women in the Olympics once ever and have 0 medals. By the numbers it's a non issue under previous rules (despite the incredible amount of ink spilled over it). People are talking about trans women here but the vast majority of people affected by this change are women who are not trans who have a "disorder of sexual development".
Is it fair to say that they can just compete in the men's division?
I'm not an expert so idk whether that's fair or not but that's what this decision is doing.
