That's irrelevant because it is illegal to go above 400ft with a model aircraft, which is before the zones balloon out any anyway. It's like saying being illegal once over or twice over matters.
The FAA Modernization and Reform Act of 2012 specifies a blanket five mile radius around airports as requiring prior approval from ATC for model aircraft.
It would be nice to add a feature to drone navigation software to prevent accidental entry into an exclusion zone.
