It all just are opinion so I will add mine.
An electrical inspector has no business requiring changes to factory installed cords (which I believe is what John is asking about) regardless of gauge, length, cord cap choice etc.
That is what a listing means to me.
Part of 90.7
It is the intent of this Code that factory-installed internal wiring or the construction of equipment need not be inspected at the time of installation of the equipment, except to detect alterations or damage, if the equipment has been listed by a qualified electrical testing laboratory that is recognized as having the facilities described in the preceding paragraph and that requires suitability for installation in accordance with this Code.
It reads to me that the inspector is required to ensure they are no alterations to listed equipment , not require alterations.
