I too was also somewhat surprised here because this is a React alternative, not an SPA alternative. SPA in my usage has always been "don't navigate to a new page in the browser, just update the content with JS requests." I thought this would be a new experimental browser or such. "An SPA Alternative" vs "An Alternative SPA" - I had a job in 2011 where we were rendering partials in Rails to send down HTML just to replace certain elements on the page to keep things single-page. We later moved to Backbone to do it more client-side on certain parts. Then I had a job in 2012 where we were in the process of rewriting the site to be a Single Page App with JSON, even. React wasn't released at these points. The SPA term was well established even then.
