I find myself just wanting to go all the way back to SPAs—no more server-side rendering at all. The arguments about performance, time to first paint, and whatever else we're supposed to care about just don't seem to matter on any projects I've worked on.
Vercel has become a merchant of complexity, as DHH likes to say.
SPAs can still be server rendered.
I think the context matters here - for SEO heavy marketing pages I still see google only executing a full browser based crawl for a subset of pages. So SSR matters for the remainder.
