If JPEG XL actually delivers the ability to serve multiple screen sizes / resolutions from the same image as proposed in FUIF: https://cloudinary.com/blog/introducing_fuif_responsive_images_by_design https://cloudinary.com/blog/introducing_fuif_responsive_imag... instead of requiring storing many copies of the same image for responsive design, that would be a godsend and would immediately convert me to JPEG XL for graphics on websites. I don’t want the complication of generating, storing, and serving the right image to the right client, there should be one image and clients should only download the amount they want.
