This whole article is about SPA and making a careful distinction between SPA and MPA as distinct concepts. aaronbrethorst has not indicated that he is confused about whether MPA and SPA are the same idea. JPM is recently building greenfield SPAs using Tanner's router. I'm writing an SPA right now for drone automation platform for 1M+ population cities. I recently helped plan out a rewrite for an SPA for a vision ML startup worth 2B. For every front-facing user property that you see there are dozens more internal tooling apps backing it, from dashboards to CMS. If you're building an SPA then Next does nothing to help you. It just gets in your way. There has been no churn for SPAs as the conversation has frozen for nearly a decade. One might point out CRDTs but that conversation began about a half decade before React was even released.
