Sadly it suffices for them to get direct government access to the endpoints. They already have that for targeted surveillance, laws like this proposal just add the possibility of mandating interfaces for total automatic mass surveillance of all endpoints when foreign device manufacturers don't fully comply. Developing or buying 0-day exploits for iPhones is cumbersome and expensive, so the law steps in.
