I am curious that you suggest that over 15db of feedback need not be detrimental. Perhaps I miss-understood.
My understanding is that one of the reasons that low feedback may be beneficial, is that the feedback is very slightly out of time with and that the human ear is extremely sensitive to this.
Like all things, I am sure that the selection of feedback is a compromise, as is everything concerning the design of an amplifier right down to the quality of components and build quality.
Some things, I am sure, are just down to plain old fashion.
