If anything, I've seen the start of the reverse happening. The warts are starting to show on the pure SPA approach, and people are either finding ways to do more SSR with the SPA tools, or taking new approaches like LiveView in Phoenix or Hotwire in Rails to provide richer experiences while still generating HTML on the server.
The heyday of "SPA is the right approach for everything" feels like it peaked at least a few years ago.
