My feeling (I've worked on EVSE's but not particularly Plug and Charge) is that standards end up being overly complex with too much potential for different implementations to disagree. Even something as simple as charging control via control-pilot/proximity signals is already problematic with some vehicles. Maybe because I'm an engineer and not a business guy, I do not understand why not implement the bare minimum that works and leave advanced cases for later.
