I wouldn't put in that exemption. The CBO has shown that it's not acting in our best interest anymore so just make it a requirement to get an FAA pilot's license to fly anything that leaves the ground. It would just require the FAA to create another endorsement to fly R/C and the basic licensing fees. Obviously, to get the license, you would have to prove to an FAA official that you can actually fly something which means a test would have to be set up for R/C pilots to pass. It would also create a way for the local LEOs to be able to use existing federal laws on those that think they are ABOVE THE LAW
