My guess would be along similar lines a sort of always on, low bandwidth, side channel. So activation and a bootstrap for the next generation of weird protocols apple would love to cook up. I don’t know at all how airdrop works, but you could see it brokered through the apple network. Or like you mentioned a find my iPhone(and lock) that works globally without needing the phone to register to wifi/cell network. Or this p2p networking they’ve been talking about, that whole thing is a lot easier with a guaranteed signal to broker the nodes.
