*No it should be Open category and Female.
Trans should be able to compete in open. Why do we need a category dedicated to men?*
As usual, women lose out. Or, in this context, perhaps I should say females lose out.
So transgender males are provided for, but not transgender females. Where would they compete? Transgender females taking testosterone would rightly be barred from the Women's class, and have as much hope of success in the Open class as women do against TW in the Women's class. Probably even less, as TW in the Women's class tend to be mediocre athletes.
Athletes generally have to make choices over what is more important to them: their sport or recreational drugs, their sport or religious practice, their sport or their social life. This is no different. There are currently female athletes with trans identity, who do not take any gender-affirming drugs purely so that they can continue to compete. But males with atrans identity will not have to make this choice?
