Ovens, induction cooking, electric car charging, dryer etc is already 240V at high amperage. With a dedicated circuit.

EU also mandates dedicated circuits for big appliances, so there is no difference in practice.

The two things I can think of are electric kettle and a raclette machine.

Tools are mostly battery powered those days. A home workshop would most likely be wired in 240 or three phases anyways.

What else are you missing?
