Chicken. I agree with what Dave said, at a high level. But where it gets to the headache part is: what is the burden of proof or how much data is needed to demonstrate that you do not affect form fit or function. Everything I have seen so far leaves it pretty much at the discretion of the Subject Matter Experts (SMEs), which leaves a lot of room to play. Maybe we need a lot of room to play.
