Fortunately, these "misconceptions" are workable enough that engineers can make a living from them, creating inconsequential products like Boeing 767s and the odd bit of cellular infrastucture. But we can't expect them to work for important stuff like audio...Feedback doesn't create distortion - it can only change what's already there. And of course the propagation delay matters - it's one major factor making implementation of feedback difficult. It won't be zero, nor does it need to be.
My gut feeling is that harmonic distortion an order of magnitude less than the speaker's or the human ear's is inconsequential, regardless of the order. IM is MUCH worse. The tone of Carlos Santana's guitar sounds wonderful to me, despite being extremely modified from its source. Play a chord through his amp... ecstasy becomes agony.
