Home chargers with dedicated sockets is three phase 400v actually over here in the EU and every single home, and even relatively new apartments have that because of induction stoves.

> every single home

Let me guess, you live in Germany? :)

Three phase power is definitely not 100% in the EU. Not even in Germany, though adoption does tend to be higher than neighboring countries.

And FWIW, I find that my induction cooktop works wonderfully on plain old 240V 40A, so I do not think it is a requirement to get three-phase for that ;-).
