THD, for instance, is calculated with a summing of the
squared levels of
the various harmonic distortions - not at all a correct
weighing of the actual perception of 'aggravation' by
these distortion components - as is known
for decades

Straw man argument. THD is not the only possible or even
commonly used means for measure or charaterize nonlinear
distortion.
