Client Hints for Server-side Image and CSS/JS Code Reduction pre-download [#2652498]

I just ready this article about Cache Hints that is currently available in Chrome and Opera. If adopted by other browsers this might be a great way to reduce overall download size based on device/browser. The browser would send the information to the site before the content is compiled and sent to the browser.

Here's the original article with plenty of details:
https://www.smashingmagazine.com/2016/01/leaner-responsive-images-client-hints

This could help reduce image size while retaining quality.
This could reduce CSS and JS code by only sending what is required for that device/breakpoint/viewport (some of that was over my head and I just skimmed most of it)

So, this is more than just a replacement for picture or responsive images as it could be used in all facets of the site to reduce code that is not used at that breakpoint.

Drupal 8.2.0-beta1 was released on August 3, 2016, which means new developments and disruptive changes should now be targeted against the 8.3.x-dev branch. For more information see the Drupal 8 minor version schedule and the Allowed changes during the Drupal 8 release cycle.

It's not "Cache Hints", but "Client Hints".

Alas, only supports Chrome & Opera for now, which means this really belongs in contrib for now. Core doesn't add browser-specific features, definitely not big-impact ones like this.
