I can see how it could be useful, but in general I would have to say no, we should not enable it.
I feel that having this tool could potentially encourage more tutorial-style answers, which we should generally try to discourage. Most questions and answers on this site should be simple enough to be answered with text and screenshots.
I think we should, because we already need screenshots to answer many of the questions. Why not have screenshots in 3D? Also, it will end up saving space where multiple screenshots are required.
If tutorial requests are too prevalent, maybe just enable p3D in the answers? That would allow people to answer questions (specifically topology questions) with a 3D model.
