>but even its most dedicated fans have given up the argument that it is the best for compression efficiency....

I will need to double check. I think even after PSY JPEGXL still excel at BPP 1.0+, and that is 85% of all images served according to Chrome. AVIF is still winning on below BPP 0.8.

Anyway we only have to wait a few more months to see AV2. Let's hope finally they have everything ready.
