The real problem is that they would have to spend any significant amount of money to do this. Finding replacement words should be quick and easy and cost nothing. Notice to Aviators is fine, so is Notice To Pilots. This isn’t hard. They can be phased in as publications are revised at little to no cost. Drone is a better term for what everyone except the FAA calls a drone anyway.
I look forward to the change away from the term Notice To Airmen as part of the complete overhaul of the NOTAM system. “They’re garbage, that’s what they are.” So lets fix them, and at the end to celebrate we can rename them while we’re at it.
