The simple geometry swap (that's what genitals on/off did) by definition does not work for Unimesh and weight mapping, and otherwise worked only for figures that had the facility built in. So, rather than having menu choices that do not work for any of the modern figures and would give rise to annoyance and questions they wisely took it out of the interface.

Can you believe it? My pub stopped having stables and a boy who would take care of my horse. They turned the stables area into a parking lot.
