BTW, you can configure the AVIF encoder to have another in-between pass or two so the quality jump isn't as big. The JXL folks just happened to go with only two total passes.

Won't that increase the total size of the image for each pass?
Thanks to AV1's inter encoding, overhead is overall minimal as each pass can refine on previous ones. Think of it as a mini-video. Because of this, in the case of images with a lot of repeated patterns, progressive AVIF encoding can actually result in more efficient images!
Looking at the demo linked in the blog post, I can make a similar quality thumbnail for a smaller size than the delta between the static and progressive AVIFs
