 > My understanding is that adding `loading=lazy` to all images can be just
 as problematic, or potentially more so, than not using the attribute.
 Images within the view port ought not use the attribute while images below
 the fold ought to.

 This shouldn't apply because `loading=lazy` only affects behavior of
 images that are ''outside'' the viewport.
