I actually wouldn't mind a little white listing. Folks like Underwriters Laboratory could serve as CAs, issuing certificates for compatibility with different profiles / standards. Then chargers could refuse to throw current at unproven devices. Of course then you need the ability to boot your charger into some kind of "promiscuous" mode for development or backwards compatibility purposes. To get REALLY ambitious, your charger could have an Internet connection and monitor a blockchain for certificate information. Some careful protocol design could let users override the DRM at will without letting cheap chinese crap factories ship exploding devices.
