I'm not selling caching as a silver bullet (and I'm not saying it's trivial to implement, either). It's just something a lot of people either don't use at all, or just get wrong. And surely, if something can be cached, it should be.

With Metal endpoints, proper configuration and lot's of resources, this is very possible.
