Hi Max1,
Well from ATC all I would expect is all care and no responsibility. It could save lives.
Perhaps once the aircraft is within say 5nm of the aerodrome, the system disables for that aircraft.
If the system was monitoring the absolute lowest safe alt for your position ( combination of Grid, route, sector for GPS/DME arrival, precision and/or NPA) and disables within 5nm of the aerodrome, it should never go off, unless visual.
Most the accident of this nature I have read about were well below height well before any circling area ( be it Visual,a ,b ,c ,d or e cat ), it could certainly help.
I accept your challenge.
