I don't think people fully appreciate the carefulness with which the FAA has approached this, nor the full scope of the scenarios they have considered.
If you look at the first FAA waivers to operate drones industrially -- 5 years ago! -- you will notice that all of the approved drones are military drones. Why military drones? Because the approved drones often had a decade or more of operational use in explicitly hostile environments and very poorly controlled conditions. Being able to reliably operate in those conditions was considered strong evidence they were unlikely to start falling out of the sky when operated under much better controlled environments and less risky conditions.
The challenge for many new drone builders is that their platforms are not built anywhere close to the reliability and resilience standards of military drone systems, which are typical the product of companies with proven aviation/avionics systems engineering experience and bankrolled by US defense spending. Even when they build systems that on paper meet this level of engineering, the lack of operational history and experience puts these drones on the slow path to approval.
Amazon getting the FAA to sign off on industrial use of an exotic drone airframe with no operational history strongly suggests that its safety and resilience characteristics are excellent, at least comparable to drones designed to survive military environments.
