I see that the tops are differentiated as "with breasts" and "without breasts", but there's no "with/without penis and testicles" to differentiate the pants patterns and that might be uncomfortable and problematic for some folks.
That being said, it's a fair point. Most of the sewing world is still rather strictly segregated between menswear and womenswear. We try to remove that distinction and just deal with bodies, but it's an ongoing journey. We're not there yet, but we'll keep at it.
