In could be useful for a drone, as it would then be able to automatically get out of the way of nearby aircraft. And, given it can be done with a $15 USB stick and a tiny amount of CPU power, probably not a bad thing to add to them... there aren't many people who'd want an aircraft to hit their drone.
Of course, you'd still need to add ADS-B transmitters to all the aircraft around here that
don't transmit their location...
