Description Dominic Farolino 2018-12-20 12:46:57 PST 
It is useful for the UA to be able to preload responsive images. The idea is to allow this with the imagesrcset and imagesizes attributes on <link rel=preload as=image>. Spec PRs and discussions:

 - https://github.com/w3c/preload/issues/120 (Initial discussion)
 - https://github.com/whatwg/html/pull/4048 (HTML Standard PR)
 - https://github.com/w3c/preload/pull/134 (Preload Spec PR (minor))
