 > I am not asking for a full <picture> support in WordPress.

 Why not? It would be great to add imho :)

 I've looked at what would it take to add full `<picture>` support to
 WordPress. The above is just one place that needs fixing, another is in
 `wpautop()`, and another is the block editor's image, gallery, media and
 text, etc. blocks. Then there is the question of adding "responsive images
 support" similar to `srcset` and `sizes` attributes in img tags. Of
 course, each of these would need a separate ticket.

 Seems that adding support for `<picture>` to the rendering of `[caption]`
 shortcode in the classic editor will only need changes to the regex here:
 Note that the [caption] shortcode is rendered differently in the classic
 editor and on the front-end. The difference is only in the "wrapper"
 element(s), so perhaps replacing `<img>` with `<picture>` would not
 introduce back-compat problems.
