Since this page is talking about SPAs, the only "entry point" it considers is `index.html`. I don't see anything against pre-rendering parts of `index.html` on the server-side -- just that the configuration embedded in `index.html` of _which_ static assets to use and _what_ the environment defines must be managed. In multi-page applications (MPAs?), among the other things that would probably have to be accounted for, you could treat all of your pages as "entry points" in the same way as `index.html`.
