hmmm - does it really matter?
I tend to use modulation instead of wiggling knobs myself, I only have 2 hands and at the end of the day it really just comes down to taste, doesn't it? - I want to move this knob 30 degrees and back every 10 seconds - just plug in an attenuated lfo - does exactly the same thing

I think it matters. The amount of error in a hand-tweaked knob will vary over time while a decent LFO will be relatively stable over time. I think we can sense that error (if not hear it), and that error is what I think contributes to interesting sound/music. They say guitar playing is all in the fingers. Keith Richards' feel will never be as precise as Steve Vai, but I know who I'd rather listen to. Of course no one else cares, but that's what makes something interesting to me.
Barring random and chaos modules, which can be unmusical in some uses, If we all have the same precise utilities, the same LFOs, Maths, Kinks, etc., there are only so many original combinations to make an interesting sound. What ultimately differentiates any of this music then? I would say the human error is what differentiates it all. Separating into utilities-are-more-important-than-oscillators (or vice versa) "camps" sort of takes away from the OP's fun thought exercise.
