Life Safety vs EM

And I think NEC should have left definitions that only apply to one section of the document within the section it applied to. This would have been one of them.

I agree, I was in it last night and I realized, all the wiring method type definitions didn't move. I think the only one that should have moved was Equipotential bonding since it was used in both agricultural and pools.

547 doesn't really have any equipotential bonding requirements or at least something it calls equipotential bonding. It does have equipotential plane requirements and so does art 682.

Though the definition in art 100 doesn't really give details, equipotential plane in 547 and 682 usually involves a "ramp" where the plane gains depth at approach points to minimize step potential as you approach something. Where equipotential bonding around art 680 applications is a hard bond that has no ramp requirement at the borders of what is required to be bonded.
