Re: [w3ctag/design-reviews] Design Review: Speculation Rules (Prefetch) (Issue #721)

Hello. We have an extension to the speculation rules syntax to allow the referrer policy of a speculative request to be set explicitly. A key use case for this is to allow a site with a lax referrer policy to adopt cross-site prefetching by using a strict policy specifically for the prefetch.

Explainer: https://github.com/WICG/nav-speculation/blob/main/triggers.md#explicit-referrer-policy
Spec: https://wicg.github.io/nav-speculation/speculation-rules.html
Tests: Mainly in https://github.com/web-platform-tests/wpt/blob/master/speculation-rules/prefetch/referrer-policy-from-rules.https.html
Chrome Status: https://chromestatus.com/feature/4694585584910336

(Note that as of this writing, the most recent version of the spec hasn't yet been published at that link, but should be available soon.)

Please take a look.
