One point on that: Tesla's newest MC (Mobile Connector) and WC (Wall connector) both use SWCAN (Single-wire CAN) to communicate with the car, and they exchange way more data than Good old "dumb" J1772. They also use this facility to update the EVSE from the car. (Car downloads update and pushes to the EVSE) This also enables Tesla to collect logs about EVSE performance, which I'm sure are somewhat useful.
This is basically the same communications protocol that's used between Tesla cars and superchargers.
