This is very true about 3 phase, but I have heard that there is interest in it being used in EU for AC charging in public garages because it can handle anything up to 277 volts vs J1772 which can only do 208/240. So they can give it 1 of the 3 phases @ 220V and it will work unlike J1772. Allegedly.

But I kind of doubt it will go anywhere when they've been forcing CCS2 on everyone.

The CCS2 AC-only connector (the one for normal charging at home, destination charging and so on) already supports 3-phase with up to 480V phase-to-phase, up to 22kW. It's larger than the NACS connector — there are two additional large pins — but not unwieldy.
