JPEG XL would like a word.

Which kind of encode settings do you suggest for conversion from high resolution RAWs or JPEGs ?
1. Lossless AVIF is a joke often beaten by WebP and even PNG. Even worse for grayscale.
2. Chroma subsampling remains a bad idea for still images unless the resolution is high enough to hide the artifacts.
3. Tooling is the worst part, AV1 encoders are basically focused 99% on video and leave a measly 1% to image; unlike JXL, of course. SVT-AV1 still doesn't do YUV444 and libaom was unusable. Fortunately, the unpaid enthusiasts were here: https://giannirosato.com/blog/post/the-multimedia-renaissanc... (and more recently https://giannirosato.com/blog/post/oavif/)
I don't see AVIF being used for lossless, which is the largest reason I'd prefer JXL to win: one codec to rule them all sure is an alluring future.
