Cross post from getzola/zola#2055:

To make our pages load faster and minimize the use of bandwidth/memory when a user does not scroll a whole page ; we can use the following attribute to make the image load only when needed (lazy loading):

<img src="image.jpg" loading="lazy" />

Is this something that pulldown-cmark is interested in? This could be configurable and not-lazy by default to be consistent with current state.
