To me it seems like the overall solutions have been pretty obvious - for drones capable of operating in IFR-only controlled airspace, the story is clear (transponder, ADS-B, follow filed flight plan and ATC instructions). For drones operating at lower altitudes in "see and avoid" VFR conditions, drones must be capable of seeing and avoiding traffic (there are some vendors in this space already). Giving commercial drone operators right of way just to make their development simpler is not the answer.
More troubling to me personally, the FAA is once again proposing rules that clearly encroach on private airspace rights. There is clear precedent from US v Causby that the government obviously does not control airspace all the way down to the ground, yet the FAA continues to propose and enact rules that would give it authority to prohibit personal use of the near airspace while providing it to commercial users. E.g. the position that the FAA can regulate your own drone flown over your own property below 400 feet, while enabling companies to do so, represents a serious encroachment on property rights.
