Most people don't disable JavaScript but beyond that edge case (I consider JS disabled an edge case) I agree that this architecture isn't necessary and overused. A single page app is great on a MacBook Pro with 2 tabs open but run that on most "normal" people's machines and it gets laggy quick.

People always mention disabled JS and SEO as pitfalls but I think performance and practicality are the obvious reasons not to do this that get overlooked. SPA architecture is something I use alongside server rendered pages. When you have one page or a series of pages in a particular user flow that would benefit from no page reloads and are heavy on interactivity then it makes sense but otherwise I can't see the value. I think developers will realize this and take a more balanced approached with a practical mix of pages rendered server side and pages that use XHR and JavaScript to enhance the experience.

How, exactly, do you know this?

Sure, it's probably a reasonable guess. I just wonder how many of the people making this claim are simply assuming it to be true or relying on some sort of analytics service. About the only way you could tell is by counting the server logs, which I'm often told are hard/annoying/unavailable by analytics advocates.
