You know your stuff. A major problem the utilities face with EV charging is that there's only 1 meter per house. Utilities actually want to offer lower rates for EV charging, but with a single meter they can't tell what's being used for EV charging vs others. Currently it's the special rate over night. We have a smart switch prototype coming out in a week that can add internet to a switch and supposedly revenue grade metering. Of course, getting things approved by utilities could take months if not years.

PG&E's EV-B tariff is specifically for a dedicated EV meter, but the installation cost of a dedicated meter + box + charger is so much that it really doesn't make sense for residential applications.
eMotorWerks especially is experimenting with chargers that have wifi + a lot of smarts built into them.
Most residential EV users will enjoy the reduced overnight rates, but probably not useful for public-service charging which usually takes place during the day when time-of-use electricity rates are at their highest.
