Many more are a problem without a knob to speed through the steps.

There's no reason an induction hob can't be run with delta-sigma over it's normal low-resolution PWM to get accurate, high-resolution average power control. 1% power accuracy is easy, 0.1% is a few bucks more per "burner".

The problem I've seen with some induction hobs is that the low power settings are basically 1 second on / 5 seconds off, which is kinda annoying when the liquid goes between boiling violently / not boiling at all. Maybe thicker pots would help smoothing that out, though.
