IMO the community shifted from SSR to SPA initially very rapidly due to the huge benefits over entirely SSR apps, but it came with some notable pain points and some new frameworks that incorporate parts of SSR have been attracting a lot of attention for solving those pain points.
A lot of leading maintainers now feel that the best solution is more of a middle ground where frameworks support both server side and client side rendering with the developers given the flexibility to choose what renders where (or on both) depending on the app's needs. React is driving a lot of this now with server side components, but there's a lot of frameworks that were doing it beforehand which has inspired much of what they're doing now.
