I don't know much about JXL vs AV1 from a technical perspective, both seem significantly better than JPEG. But JXL has the practical advantage that it can losslessly recompress JPEG images for a size improvement without an image quality improvement. When converting JPEG to AV1, you're stuck decompressing the JPEG into raw pixel data, with JPEG artefacts and all, and then compress that pixel data with AV1, so you get the artefacts from JPEG and the artefacts from AV1. Decompressing the resulting AV1 image will result in different and almost certainly worse quality pixel data. So the ability to do a risk-free lossless conversion from JPEG to a better format and get a size improvement is a pretty darn big domain that's not served by AV1.
