Comment:

 As the savings aren’t huge, and people don’t agree on the UX/aesthetics
 arguments—shouldn’t it be the author’s call? I.e. just generate all image
 sizes with the same ‘progressiveness’ as the originally uploaded image?

 FWIW, on a slow connection I find it very irritating to watch a header
 image download in baseline form—I don’t have a clue what is to come; while
 with a progressive image, I have some idea of what to expect, much
 earlier.
 (Looking forward to AV1IF!)
