I personally agree with the precautionary principle and think there should be stricter requirements for certain classes of new products, but the best solution is probably some type of compromise based on level of newness and possible danger. The core problem is the "unknown unknown". There's no upper limit to how much testing you should do to ensure a product is safe because the space of possible dangers is nearly infinite. So any policy will be a balancing act of false positives and false negatives and what levels of each are tolerable. I think this is the proper question and it is not an easy one to answer.
