My 10 cent understanding of this new Part 108, it is really tailored for the Walmart and Amazon's of the word. The certification requirements are more akin to Part 121/135 level operations and would be more expensive and onerous to the average drone operator, even the professional ag drone operators.
The way it has been described to me, is that these high end drone delivery operations would essentially get a block of airspace, almost like a TFR, that is stood up during operations. Those blocks would be at lower altitudes, and avoid airports, helipads, and approach zones to both. Manned aircraft will be expected to avoid said airspace, which except for helicopter and crop dusters we probably wouldn't be in anyway.
One of my initial thoughts based on that information, which may be incorrect, is that our maps are about to get crowded with all this new Special Use airspace. It will become useless noise that will be ignored, much like the 10,000+ tower and obstruction NOTAMs we get in every briefing.
I also question the business case for drone delivery. One problem is noise. Even the smallest drone these days sounds like an angry mosquito. Multiple that by 100, the public isn't going to be happy. Another problem is potential theft or loss of product. What will happen when today's porch pirates start taking swipes at these drones? The other issue I see is liability. One of these drones has a failure that crashes into someone's house or car, breaks a window, or potentially injures someone, I'm sure insurance underwriters are going to love this one.
Or maybe I'm just getting old...
