I would say we might as well have 400V as 230V and more or less halve
the conductor sizes. Much more than that is getting silly though.

I'd vote for the standard domestic supply being 3x32 A (3-ph) instead of
1x100 A. Then we'd have the advantages of 3-phase for motors and
rectification, and could have 400 V appliances like cookers and showers
hooked-up with 2.5 or 4 mm^2 cables. Proposals now required for a compact
5-pin 16 A plug & socket...

There's nothing stopping you having that now.
The range of appliances available might be a bit limited to you.
