The OP of this thread was specifically about transwomen in women's sports. The ongoing debate about trans rights in public policy arose from that issue. The place for your biological nuance is the other thread. Here, everything is pretty much cut and dried, as far as policy goes. Your attempt at nuance creates confusion where none need exist. It's also often a hallmark of people who want to use that confusion to transcend sex segregation in women's sports, prisons, and other spaces. If that's not where you're going with this, then consider taking it to the "strict definitions" thread.
