Doesn't matter if you disagree, it is still an optimization tool that can be used in some circumstances.
The data is most definitely cached if the server sets the cache expiry for the HTML file, so "anti-caching" makes no sense and is completely orthogonal to the optimization.
If the page's critical CSS is small enough you can deliver an HTML page where the initial render a) happens sooner, and b) is a complete Skelton of your layout + initial content. All at the low low price of ~0 additional client-server roundtrips.
Fun fact: facebook inlines a `style` tag and all HTML necessary to render their initial loading screen. It isn't what I would call "above the fold" CSS, but it is what is referred to as "Critical CSS".
Aside: the most popular and most-used SPAs are scrollers: twitter, instagram, facebook, github, etc, so now I wonder if you might be just trolling?
