Exactly what I was thinking - an increase in OAT increases the speed of sound, so the aircraft would be even further away from a Mach limit than before. And IAS is dependent on pressure, not temperature, so there'd be no effect on an IAS limit. I'm struggling to see why the aircraft would see any increased airspeed to protect itself from.
