First, I have not read any of the attachments, so forgive me if what I'm going to say contradicts the content you guys have read.
BUT...
A friend of mine that is loosely tied to the FAA process told me that the process the FAA was planning for commercial use of a UAS system weighing less that xyz weight (I thought he said 54 lbs), was only going to require the operator to register the configuration of his aircraft, the allowable operators, and maintain certain records such as flight time, aircraft maintenance of configuration changes, and that it was *not* going to require any kind of qualifying of requirements of the aircraft. He was stating that the FAA understands that the lighter end of the UAS spectrum was small operators with small(er) budgets and that they intend of fomenting that industry through light regulations.
Again, all of this was word of mouth from my friend, and if these regs state otherwise, it's more than likely I misunderstood him, or it has evolved beyond his loose involvement.
