I'm also wondering why you'd do this. You can crop in software afterwards, which gives you a little more freedom to expand or shrink the crop area for the best result. The only benefits I can see in having the camera do it for you are (i) you don't have to bother when post-processing, and (ii) it presumably allows you to squeeze more images onto a card. The crop factor certainly isn't making your 70-200 any longer, you'd need a teleconverter for that.
