From my experience, there are several thousands of people/companies using UXWizz and so far no one has requested this feature yet.
But now that you mentioned, it seems like a pretty useful feature, especially if you can see top performing pages/articles.
I think one reason why people don't care about the specific analytics for a page is that they usually write pages/articles for SEO purposes. To see how well a page is performing SEO-wise, you usually go to Google Search Console (or Bing Webmasters) and see search terms/click-through-rates for that page.
Also, time spent on a specific page is not that useful, typically you want to see: if people are buying stuff, where do people that buy stuff come from and what page do they land on.
