It is not the kind of caching that the post I'm replying to is advocating ("the entire app can live offline and even cache data in local storage"). I mentioned the caching I am doing to point out things aren't so simple. I do mean quite literally that none of my API HTTP responses have a caching header (assets are coming from CDN with very long cache life).

It might be more fruitful to try to explain why I go against that instead of simply saying I do without a rational argument that can be responded to. If anything, the thread pretty clearly revealed someone is extremely biased to server-side web frameworks and is unaware of the progression of client-side web APIs.
