Since Google has already established that JPEG XL is objectively inferior to AVIF [1], and some of its employees, speaking for themselves have also shown similar testing results on twitter. I would actually ask Google why would they be interested in supporting an inferior image codec?

JXL can losslessly recompress the billions of JPEG images out there, which AVIF cannot.

Also, from your link:

"JPEG XL has better lossless compression compared to WebP, which has better lossless compression compared to AVIF for these images."

I would then argue that the superiority of AVIF over JXL is a point of view at best.

Great comparision! as you can see on the linked page: https://storage.googleapis.com/avif-comparison/verification-...

They are comparing production encoders of AVIF, JPEG and WEBP with the reference implementation of JPEG XL. If anything, it is amazing to see how fast the reference implementation is. Remember initial AV1 days-per-frame perfomance?
