Which is acceptable to the code.

That is what I stated "per code".

- 200.7 Use of Insulation of a White or Gray Color or with Three Continuous White Stripes.
- - (A) General. The following shall be used only for the grounded circuit conductor, unless otherwise permitted in 200.7(B) and (C):
- - (C) Circuits of 50 Volts or More. The use of insulation that is white or gray or that has three continuous white stripes for other than a grounded conductor for circuits of 50 volts or more shall be permitted only as in (1) through (3).
- - - (2) Where a cable assembly contains an insulated conductor for single-pole, 3-way or 4-way switch loops and the conductor with white or gray insulation or a marking of three continuous white stripes is used for the supply to the switch but not as a return conductor from the switch to the switched outlet. In these applications, the conductor with white or gray insulation or with three continuous white stripes shall be permanently reidentified to indicate its use by painting or other effective means at its terminations and at each location where the conductor is visible and accessible.

"per code" means that the white is permanently reidentified to some other color besides white (or green), say "black" or "red".

I know, that permanent reidentification is never done, but that does not make using that cable improper, it makes NOT "permanently reidentifying" that white conductor improper.

You DO always write that up as a code violation, correct?
