I'd rather the FAA take a proactive, and active, role in creating rules which allow operations and enforce existing damage and nuisance laws. Letting the FAA "take it's time" is like telling ID that there's no rush on getting Duke Nukem Forever out as long as they do it right.
Drones are tricky.
The FAA has no choice BUT to take it slow because there are a lot of stakeholders to consider - including regular airspace users, air traffic control, etc.
I mean, there's a hobby advisory circular that's just that, advisory. People flying drones under those terms are still deemed to be flying aircraft, and there has been a case where a drone pilot flying their drone in an unsafe manner has been charged under the FARs (it was initially appealed but the NTSB upheld that advisory circulars were not law).
At best, the FAA can apply what they feel is appropriate, i.e., advisory circular rules. But if your drone exceeds it, then it has to be part of the big boys including see and avoid, communications, transponders, etc., if it comes close to controlled airspace.
And then there's the whole controlled part of it - if it's in controlled airspace, then it needs to obey ATC. We've already had issues where drones piloted by people who really do know better still not properly doing their part. Enough so that the FAA had to basically declare areas of airspace as "drones only" because testers couldn't assure that their drones would participate properly.
then there's the whole taxing thing - if drones use ATC, they need to pay for it. Right now aircraft pay for it through fuel taxes (thoughts of user-based taxing keeps coming up as the airlines keep proposing it, though it gets shot down because GA objects - they already pay the taxes for it).
You want agile drone development, you need to go into a place where airspace is controlled and there aren't so many stakeholders. China is one, for their military controls all airspace. GA is practically non-existent (the military has started allowing local GA flights though). Now there the only stakeholder is the military.
Europe works too since GA is suppressed through high taxes leading to mostly only airlines having to be consulted.
