Comment (by joemcgill):

 > So what happens if we generate a srcset that has some invalid URLs, and
 add it to an image?

 I think @aaroncampbell brings up a valid concern here. Without a way to
 respect any filters being placed on `wp_upload_dir()` it's possible that
 we could add invalid urls to the `srcset` attribute. The browser has no
 way of knowing if a source is valid or not during the selection process,
 which could result in broken images.
