There is NEMA 14, which has hot,hot,neutral,ground, but I don't think anything lower than 20amps is available, and that's a locking one, 30 amps is available without locks, but 30 amps at 220v is a lot of power for household outlets. You'd need larger wire in the walls, not just more of them.

Any sort of outlet upgrade would need a really good plan for how to make it viable, because even if 100% of new construction used the new outlet, it would be decades before you could sell devices that relied on it.

I have a 20A 220 circuit for an electric kettle with multiple 6-15Rs. It has a 20A gfci breaker.

You could include a second cable with the teapot, and wire it to work with 110 or 220 depending on which cable is used. This is already reasonably common. I have plenty of useless European cables laying around to prove it.
