Using Saliency in progressive JPEG XL images

AVIF should be completely cancelled in favor of JXL. A native designed-for-images codec is so much better than "use video codec for one frame" in countless ways. Indeed progressive being probably the biggest one.

Oh, and Apple might be less hostile to it, because it's not based on an "anti-MPEG" video codec.

I think AVIF is a great replacement for GIF (the acronyms even rhyme and all!). For short-video-without-audio, it's as good as it gets.

For still images though, I don't really see any major advantage of AVIF over JXL except AVIF being a bit older and already enabled by default in Chrome. I do see several advantages of JXL over AVIF though.

So the way I see it, the future is:

AVIF instead of GIF (and APNG and animated WebP)

JPEG XL instead of JPEG (and PNG and still WebP)
