To be fair, the FAA has to follow processes - including a cost/benefit analysis and public comments (can be bypassed only if it's judged to be an air safety emergency). Plus, the FAA moves at the speeds of bureaucracy (i.e., slow, slower, and slowest).
The NTSB has no such obligation - they can recommend anything they see as having potential value.
