I had responded to the AMA / FAA during the NPRM ( Notice of Proposed Rule Making) stage of the new act, asking for them to specifically include statements that Control Line Model Airplanes were either exempt or non- applicable to the rule. The reply was that CL planes are not considered "Aircraft", due to the fact they were continuously tethered to the surface.
It makes sense - kites routinely fly 10x higher than a C/L aircraft, tethered balloons are used for advertising and rides, etc, they would have to include all these other "tethered" flying objects.
The challenge will be the general public, they don't read CFR / FAR regulations, they depend on the media for their general information, and the media focuses on the rouges and rebels, so that is what the public thinks.
Example: the infamous FCC 1991 RC frequency "Narrow Band" rule. I flew R/C then, sent my radios in to Futaba and got them Gold Stickered. They were now legal or use all across the US, even though 1 was AM band.
Fast Forward 5 years, and I was told multiple times by various Club Experts that my radios were " Illegal" since they were not either FM or PPM or PCM, whatever the latest craze was. When I would press them for details, they usually couldn't tell you where to find the regs. News Flash, my 25 year old radios are still legal! And my C/L planes are too!
