I'm not sure it's as simple as that.
AF Fine Tune can be a very useful feature, but is not an automatic solution to every problem with "softness". Nikon say (in camera manuals) that it should only be applied when a lens/camera focusing error is present. It definitely calls for some care and skill to set up and perform the necessary testing. Even then, with zoom lenses in particular it's possible that applying an adjustment which works well at one focal length and focus distance may make things worse at other settings.
>It's nothing to be obsessed about...
I agree, but I see many people treating it as "normal procedure" when it's not intended to be.

My view is different - to me it seems to be pointless to tune focus if a basic lack of skill and knowledge may still prevent someone getting good results - and may even get in the way of applying the adjustment accurately.
But at the end of the day each of us must make our own decisions
