I used 780 to call attention to the language related to structural steel. I don't think that it relates to metal studs.
If the metal box was secured to a metal stud (and I was thinking about Romex in my last post) the EGC would be terminated onto the box and it would ground the studs.
Like you, I always recommend use of a separate EGC and agree.
I guess the proposal should be related to the use of "nonmetallic wiring systems and romex."
PS: I edited the reply above, I probably should slow down a little!
