GPS makers have been designing their receivers under the rules the FCC has set forth for decades, that the bands surrounding GPS are for sky level signals. I wouldn't call that "lazy".
Imagine if the NTB suddenly decided that it would be OK for people to drive tanks at 1000 MPH on existing highways. Would you call carmakers "lazy" because cars currently on the road wouldn't be safe to drive anymore? Or would it be OK to tell hundreds of millions of people to replace their cars immediately at exorbitantly higher cost?
