NS is very accurate. The point at which it might break down is on extremely tiny scales that don’t actually matter.
It also breaks down at sonic shockwakes, but not in a fatal way. NS divides by zero at sonic shockwaves and real air has a very short (but present) gradient. The macro predictions are identical beyond the precision of most measurements.
Also, NS is newtonian, so relativistic stuff breaks it.
I would not disqualify the NS based on a few innacuracies at extremes. It is the name of the wind for all practical purposes. You will not encounter the problems with it.
