Comment:

 It looks like both https://validator.w3.org/feed/ an
 http://feedvalidator.org/ don't recognize the new `srcset` and `sizes`
 attributes in feeds.

 I'm not sure if it qualifies as a bug, as the feed is still valid, and
 these notices are recommendations, not errors.

 We could probably bail early from `wp_make_content_images_responsive()` if
 `is_feed()`, see [attachment:35043.patch].
