Context: Even though Chromium has native support for AVIF, a very nice image format, Microsoft goes out of their way to remove it from Edge, which is a chromium fork. Jpeg XL (JXL) (not to be confused with Jpeg (JPG) or Jpeg 2000 (jpg2k) ) is another nice image format, which, IIRC, is only supported in Firefox.
I said it in another comment, but I’m actually working on a website right now, which happens to lazy-load a lot of images with Javascript. I think I’ll store all the images in webp, avif, and JXL formats, and have the javascript code automatically load the one which is supported by the browser. Hopefully if it takes off, it can promote support for modern image formats!
