> Because transferring tags back and forth is insanely wasteful You are full of superlatives but short on arguments. As the number of pages you load tends to infinity, this might be true. In practice, loading a couple of 3KB pages is much better than loading a couple of 1KB data blobs plus a 500KB JavaScript app bundle. It is also more memory-friendly, more compatible, and better for SEO. As for wasteful of bandwidth... how big can HTML get? Is the bulk of your bandwidth cost really taken by HTML?
