Client-Hints

We all know UA sniffing sucks. But it's really common because there is a real need to know stuff about the browser on the other end when serving up content and resources. What if instead of just a UA string, we got information about the browser in the headers as well? Client-Hints aims to be that. It's in the RFC (Request for Comments) stage now and there is great discussion about what kind of information it should be making available.
