At least a few years ago, they would openly recommend it for non-Teslas.
I thought NACS brought some changes to Level 1 and 2 that aren't backwards compatible with J1772? I know there's an oddball voltage in there so you can put a NACS charger on a lamppost where J1772 would require a transformer; but I didn't think there were protocol issues too.
J1772 is 120V or 208-240V. Those are by far the most common voltages in the US. (208 is what you get when you take a US 3 phase system and connect to two phases - this is somewhat common and most people don't know or care that their apartment is wired like that). I have seen other voltages at industrial sites, but I wouldn't expect that in a lamppost.
