I believe all models should be anatomically accurate in all forms, but there's still courtesy to keep in mind, for those who don't feel comfortable with it, for whatever reasons.

So build models with both options, since only having one or the other alienates those who would prefer the opposite. 

Worries about it's perceived consequences have their merits in certain regards, but no one has ever been able to shut down the porn industry or even take a chunk out of its exponential growth. It has too much influence on entertainment and its related technology, and its video sales alone are roughly a third larger than mainstream media sales. It's pretty much accepted that porn is the #1 reason the internet exploded in growth in the 90s, and is largely credited for the devlopment of HD cameras (somethng I picked up while in film school, though I've never actually researched it myself). Too many detials to really go into where adult entertainment influences things you'd never even think of, but if anything is certain, it's that porn will never go away.

The only problem I see is being able to morph a fully detailed adult figure into a child sized figure with all the adult parts. But the thing is, that can already be done by using content that already exists. So if it were going to cause problems, why hasn't it yet?
