Explainer

Specification
https://wicg.github.io/nav-speculation/speculation-rules.html

Summary
An extension to Speculation Rules syntax that lets the browser obtain URLs for speculation from link elements in a page. They may include criteria which restrict which of these links can be used.

Blink component
Internals>Preload

Motivation
Provides a more powerful and convenient mechanism for specifying URLs for pre-navigation speculation, instead of directly listing URLs. It takes into account current links in the document (which can dynamically change), and allows developers to specify pattern-based allow/deny lists. This is more convenient in scenarios where a page contains a large number of links or dynamic content, and it may not be convenient for the author to synchronize this information with a separate list.
