Client Hints has been added to

Short answer: it is not available by default in the 4 major browsers so it is not yet usable in production.

You can test with chrome canary.

It is behind the chrome://flags/#enable-experimental-web-platform-features flag.  Turn that on.

I think Google is looking for feedback on it.

The Yubico developer test page lets you set those flags.
