If I understand it right, a grounded conductor will be required to be pulled to eash switch. In a 3 and 4 way swith loop, three wires are required to run between the switches just to switch the hot leg. How to you get your a grounded conductor to the other switches without violating 300.3(B)? Violate 300.3(B) could likey generate some CEMF and FUBAR the electronics in the switches the new rule call for.
Not only the NEC is a safety manual. Its becoming a designing manual. By bringing a grounded conductor to each switch in no way makes the wiring any safer. It's a design issue. If shhh-poopheads are using the grounding conductor as a grounded conductor, the shhh-poophead will still do what he/she is doing til someone holds him/her to their actions.
