NACS is fundamentally incompatible for 3-phase power. You need a live, a neutral, a ground, and two extra wires for each extra phase.
I’ll take my chunky connector with 22kW over your sleek one with 7kW :)

I submit a counterexample of the huge network of Tesla superchargers that can do the job quite well with the NACS connector.
maximum power output of 600 kW and a maximum current of 615A at 1,000V
The practical limits are based on the cars and their batteries, not the charge port.
What was the problem again?
You want to charge as slow as possible for your need, but needs do vary.
> What was the problem again
Why would I want to wait for more than I have to? e.g. I forgot to charge during the night and need to go on a trip in a few hours. Now I need to find a fasts charger and pay for it instead of charging at home, why exactly?
You're referring to DC fast charging. For AC charging the NACS is limited to single phase. This is a charge port thing, not the car or battery.
Which doesn't matter much in the US, but it does in Europe.
That does make it useful to charge it in a few hours in the afternoon, instead of having to wiat the night.
All houses have triphasic power (usually 35A per phase, sometimes 63A), and all apartment buildings with electrics from the last 2-3 decades provide triphasic power to each apartment as well.
Our ovens and cooktops expect triphasic power, with a two-phase downgraded configuration for backup.
Same for Sweden I believe.
I have a 22kW CCS charger at home and it is seems perfectly fine.
The cost of the supercharger isn't really relevant either, most US homes are gonna max out at 200 amp service which is a max of 48kw, but realistically probably half that due to your house needing electricity and a single custom circuit unlikely to be over 100 amps.
