Suppose you have *real* faders which have a range of 127 mm.
That's not far from a typical size on a pro mixer. 
Would you ever adjust them by half a millimeter ? 

127 steps, provided they are mapped well, and zipper noise
is avoided by interpolation or filtering, should be enough.

The real problem is that many SW mixers

* don't use a good mapping,
* and don't have any other gain controls.

The latter may force you to use the fader in a range
where it has bigger steps.
