Earlier quoted context omitted.
I get your point, but what I am saying is that if you are not careful, you can easily overheat empty teflon-coated pan on an induction stove and create toxic fumes, no oil required. And you don't even have to forget about the pan. Just setting the stove to high temperature when the pan is cold can quickly create superheated spots due to the way induction works (the temperature sensor is hidden and so it "lags" a bit)…
It's completely unnecessary to heat as cautiously as you describe. Even the worst performing induction burner is not going to heat the pan hot enough unless you do it deliberately, or just completely forget it. Also, maybe you do it differently, but I put the oil in before heating - so if I had stainless, with oil, heated in your "unsafe" manner I would have toxic smoke in the air long before I would have fumes from…
I fully understand that this may just be the manufacturer covering his, um, behind. But I am not going to risk it.
