I don't see the current J1772 approach as bad.
The obvious downside is that the connectors are between outrageously expensive and unavailable. But the only inexpensive power connectors regularly used outdoors that I can think of are used to hook up boats at dock. And those aren't cheap, especially when you move above 30 amps.
The big plus is that the base power is a standard 220V at 30 amps and it's a trivial pilot circuit to turn it on. You only need a smart circuit if you want to draw more power.
Just plan on 220V at under 30 amps for charging now, and buy a J1772 connector pair when they drop in price. By the time the higher power modes are actually standardized, there will likely be an inexpensive module to handle the smart side.
