           Version: WebKit Nightly Build
          Hardware: All
                OS: All

The Priority Hints spec is in the process of being merged into the fetch and HTML specs and allows for site developers to hint at the relative fetch priority for various resources.

The main changes are:
* Adds a "priority" to fetch's Request and RequestInit classes that uses a string enum of "auto", "high" or "low"
* Adds a "fetchPriority" attribute to the IMG, PICTURE, SCRIPT, LINK and IFRAME html elements with the same enum values

Existing spec: https://wicg.github.io/priority-hints/

This was shipped in Chromium 103 and Mozilla is working on an implementation so it is now in the process of being moved into the HTML and fetch specs.

The main use case developers are currently using it for is to tag "important" images on their pages so that they load sooner than the would naturally.  Chrome usage from the field can be seen here: https://chromestatus.com/metrics/feature/timeline/popularity/2738
