Can someone summarize the issue with JPEG XL? Is this something that really matters? I've seen this mentioned a couple of times in the last few days but I don't see what the big deal is, is it really that necessary?
Now several formats are competing, most notably AVIF (which is basically just single AV1 video compressed frame) and JPEG XL. JPEG XL might be slightly better in some cases (as AVIF is based on a video codec) and most importantly it's backwards compatible with JPEG. So this means we can re-encode 30 years of JPEGs to JPEG XL without image degradation. Having a wide support would help immensely to make the format standard as otherwise everybody will just continue to use JPEGs. Google is somewhat against this as they already have support for AV1 and thus don't need to maintain a separate codec for JPEG XL.
