" Preliminary EMI testing showed that there was no measurable impact on conducted emissions when the second stage Y capacitors were removed."
Methinks this would be an unusual result for many power conversion and drive circuits, and too broad of a design statement for my simple little mind to cover. There is a reason for pi filters in this configuration. So we have opposing forms of safety requirements and definitions of emissions test conditions. This is Mr Perkins' "Elephant".
