I think you're missing the point. It seems that you are either talking about "Toolbar" PageRank, which I don't think anyone has even truly believed represented how Google evaluates pages (or PageRank, for that matter), or you're talking about the original paper on PageRank, and a particular implementation based on those specific criteria.
You won't find many mentions of either these days, because the SEO and search engine world has moved on. But then, there's never been any way to really measure PageRank outside of Google itself, so discussions have never really been about that specific term at all - but about the actual impact of algorithm factors that revolve around citations and third party information about a site.
