I think this a good thing. Continuing to study the impact of drones is better than a definitive ruling. Once drones are more widely used in delivery services, like Amazon and Walmart are exploring, I feel that it will limit municipalities and states from passing more restrictive drone laws and ordinances. The Federal case Singer v. Newton addresses this but it will be a legal mess with each area until the case is upheld or the higher courts choose not hear the appeals to the case.
The FAA appears to have taken the position that drones are a technology and use that needs regulation but have not reacted with dogmatic regulations. The current Federal legislation is seems more about creating reasonable safety regulations.
