I guess, you never tried to use DAZ3D.
I don't really know if that has changed, but, about the time MoonBox started this, I also made some attempts to use it. Since I am also a hairy pussy lover, I tried to put some on the characters I was creating.
Let me tell you, what a fucking pain in the ass. It took you FOREVER to align it correctly. But, if you had to move the character, you would have to start all over.
So, the most likely reason girls aren't hairy (besides MB tastes, obviously) is probably Time. This game has a launch schedule of 1 update every 15 days. With a rather large amount of content (for such a short time), this would be far less if the Dev would have to spend his time positioning bushes in every scene.
With the new GPU's rendering is no longer the barrier to image production, it is the posing and scene construction. While DAZ3D is good enough for some of it, it is notoriously bad for others, like these "extras" that need to be positioned separately. It is not only rage inducing, but quite morose to do.
No, the Dev quite probably doesn't need any lessons about women's bodies. I am sure he would love to spend hours looking at them, but, I don't think it is for learning.
Maybe you should tone down a bit on the presumptions? Or, not. Some people enjoy looking like jerks.
Peace
