William,  My own on going test - experiment has been to rely on the frames 
getting grounded by the rack. I too think the individual ground wire strung 
panel to panel is stupid and a waste of time. Supporting this hypothesis is 
100% ground continuity to every module frame and the main rack. I have tested 
every installation for ground over many years and never had an ungrounded 
frame. And I have gone back to old jobs and checked years later. Still good 
continuity.

I think the language you found clearly gives the option to ground the rack.

Don
