Img support for size/srcset

In this way there is no css involved :-)

I'm not sure I understand. How do responsive images relate to reducing layout shift? The fundamental problem is when an img lacks width and height which is true for images that have size/srcset as well as those which lack these responsive image attributes.

Reading as example https://web.dev/swappie/ confirm that give the right width/height sizes to img tags is important.
Also this will avoid to add css code and you can have a html tag with everything ready for a copy and paste.

So do you mean supply width and height to a provided img instead of adding the media/container queries with min-height?

This would essentially be the same as I've proposed in #3 but specific to img elements (and video).

I think yes, as often there are issues with images in LightHouse and this can help on understand what's going on without debugging to much.
