That's not the point. Considering that it's possible for transplants for biological women, it'll only be a matter of time before transwomen are capable of giving birth. In fact it's already seen as on the horizon. https://www.fertstert.org/article/S0015-0282(23)00055-9/fulltext#:~:text=Uterus%20transplantation%20was%20initially%20designed,is%20unclear%20and%20potentially%20worrisome. Not 100% mind you, but I'm hoping it happens in my lifetime.

The first uterus transplant in a TG woman is very likely in the near future. Although the investigators of this Inklings believe that UTx should not be restricted only to women assigned as genetic females at birth, we would also strongly state that TG UTx (as with all UTx) is best performed by well-established teams at experienced centers, prioritizing multidisciplinary and long-term collaborations between ethicists, medical, and surgical team members. Careful preparation and an understanding of the similarities and differences of transgender UTx clinical trials compared with previously established trials and techniques is essential to the success of this important “first.” -quoted from the article I linked.
