That's not actually all that crazy - I remember seeing a proposal for an electrical plug which had voltage and current negotiation - no power gets supplied until the handshake gets done. Makes the plug itself very safe (and you can have central transformers to provide 110v, 240v, 5v etc throughout your house).

Later you will also get things like 'Not for use in your region' as a part of handshake and a heap of materials, that cannot be powered on.

Me, cynical? Nooo....
