3 years ago We're not adding new features to XMLHttpRequest. FetchObserver is still something we plan to add to fetch() to address that shortcoming.

Fetch already supports setting referrerPolicy. But as you know, Fetch is not always a better API than XHR for AJAX, such as progress updating, etc. So adding support for referrerPolicy in XHR will be helpful.
So far I can only come up with an ugly workaround to support standalone referrerPolicy for every XHR request ---- just create a tag
<meta name="referrer" content="{any referrerPolicy you want}">, and insert it into DOM before sending an XHR request, then remove this<meta>to clean up. But the global Referrer-Policy setting of the page will not be restored as it was after the<meta>being removed. I tested it on Chrome 87.
