Induction hobs also have the similar property that only the pan is heated. If it is removed, the surface cools down even though the power is still on.

Yes that’s actually what these flex zone hobs use as well. They just spread loads of smaller inductors over a larger surface so it does not matter where you put the pots. The main difference is being able to control the power per pot rather than per predefined zone.
