Re: [w3ctag/design-reviews] Priority Hints API (Issue #704)

Priority Hints has been in origin trial in Chrome for a couple of months at this point and the developer feedback is summarized [here](https://docs.google.com/document/d/162dym7j0PbpoMvle58gO9DDqpQFOvvmqwu1OIJ1IEzQ/edit?usp=sharing).

The feedback is all extremely positive with a lot of excitement for launching it beyond a trial. There were challenges for some sites with the origin trial framework itself but none with the actual feature. Most of the developers experimenting with it right now are using it to boost the priority of important images (and to improve the largest-contentful-paint in particular).
* Very easy to use and integrates well with picture, srcset and sizes (which is very difficult to emulate when using preload for similar purposes).
* Decent performance gains for some sites that ran field trials, even for already highly-optimized sites.
* For everything except for scripts, there aren't good ways to get similar effects. Resrtructuring the entire page and using preload liberally can get close but is very difficult to get right and to work well across browsers.
