... but this was already the case before induction cooking?

There's no getting around Ohm's Law, so any serious consumer is going to have its own transformer to avoid either having massive last-mile losses or insanely thick cables. A large shopping mall will already have multiple transformer stations (and the associated 10kV cabling) to power all the lighting, advertising displays, air conditioning, and so on. Adding induction cooking to that is almost a rounding error.
