Agreed, Greg.
Part of the issue is that the manufacturers who used the ground as a current carrying path were very dodgey about exactly how much current they were pulling, not to mention that every one of the fancy switches was adding more and more to the ground wire.
That's when NFPA took notice and changed the Code rules for neutrals in switch boxes.
P.S. Just so everyone else on the forum knows what you and I both already know, IAEI reviews the Code so its members are well versed in the changes but they have nothing to do with revising or changing the NEC.
