I agree with what you're saying, but many, and I mean many, single page web applications get used for things that are essentially Web documents. If you're building a game or something interactive, I get it. But many SPA's are used to give database-backed forms a pretty skin. It's the overuse of Javascript in this way, and the lack of graceful degradation for forms like this when Javascript is disabled, that I think is beginning to create concern.
