This is the reason one of the main points of the ARC was to "determine if the self-regulation of model aircraft should continue".
The FAA may not grant the AMA as much as it thinks. The FAA can exclude any part of the ARC recommendations it chooses to, including the AMA request for CBO exceptions. I would not be surprised if the FAA excludes exceptions for CBOs. They could easily say "These are the rules for everyone" period. Like it or not that would be fair.
