SPAs: theory versus practice

What about real-world [SPA] websites that aren’t built by JavaScript framework authors?
The important thing, I think, is to remain open-minded, skeptical, and analytical, and to accept that everything in software development has tradeoffs, and none of those tradeoffs are set in stone.
