Certainly, rankings and traffic to every single page that is left non-supplemental has dropped to practically nothing since most of the site went supplemental.

Nope. One site I observe lost 99% pages to supplemental, but kept page rank on those pages that did not go supplemental and some brand new pages got a page rank.
