I don't know - just like painters once ceased to try to create the most realistic looking representation and started taking pleasure in exploring the paint and the canvas, I figure that a recording is a recording. A bit of noise can add life and depth. In small, subtle doses, it helps provide a frame of reference.
But that's me - I like me
some noise. It's part of life, even before birth. I'd probably be very disoriented if I sat down to play guitar and suddenly heard nothing but the sound of the instrument, in its absolute purity - no room, no background noise, nothing else. I'm sure it would sound terrifyingly unreal.
