I think it's less of a revision and more a return to a core meaning.

Privacy isn't a mechanic, it's a capability, and most reasonable people DO expect, implicitly, that that they can travel unremarked under most circumstances.

I think most people would agree that a government drone swarm specifically tasked to follow you everywhere in public (loitering outside buildings) would be an invasion of privacy. Especially when it is illegal not to be wearing some equivalent of license plates.
