I think if you do a google or search on this board it is actually possible but requires taping down a contact on the lens, or changing something. From memory there's a video somewhere showing someone doing it.
The reason they restricted it is because they weren't confident enough that the focus was good enough to hit f2.8 all the time. Having said that there's not really that much difference between f3.5 and f2.8. Also you probably don't want to autofocus anyway - it's rubbish at tracking, especially with SSM and SAM based lenses.
What is useful is one shot focus off the FS700 for example. It will close the iris down, focus and the return iris. It's quite useful for a sanity check focus at times

there is a diy fix which involves making a simple modification to the lens - http://www.portreti.lv/how-to-hack-...k-with-open-aperture-in-video-mode-autofocus/
