It's a really weird situation, but using public transport WiFi cured me of this thinking.

The amount of times that the initial HTML, CSS and JS came through, but then choked on fetching the page content was insane. Staring at a spinner is more insulting than the page just not loading.

That being said, I'm not a huge fan of RSCs either. Dumping the entire VDOM state into a script tag then loading the full React runtime seems like a waste of bandwidth.
