You’re getting a downvote treatment but I kinda agree with you that SPA shouldn’t change history. But also, that was like the first versions of SPAs. The name stuck around (hello AJAX) while the underlying infrastructure and mechanisms great improved.
"Page" is clearly too ambiguous as almost any acronym will be. The main tenet of a Single Page Application at least used to be, before it was buzzworded into ambiguity, that the browser loads everything it needs once and makes round trips only for new data or incremental functionality. I think the same definition is still applicable, though. It never had anything to do with the information architecture of your UI or whether the majority of the screen might change between pages. And nothing to do with the URL or history; that's all orthogonal and now can and should be done with deep linking and the history API to allow people to have faster feedback and still interact with sites in the browser the way they always have.
That's not true. Wikipedia [0] has a nice summary:
> A single-page application (SPA) is a web application or website that interacts with the user by dynamically rewriting the current web page with new data from the web server, instead of the default method of the browser loading entire new pages. The goal is faster transitions that make the website feel more like a native app.
