Note Chrome ATLs formally declaring yesterday: "Since JPEG XL was last evaluated, Safari has shipped support and Firefox has updated their position. We also continue to see developer signals for this in bug upvotes, Interop proposals, and survey data. There was also a recent announcement that JPEG XL will be added to PDF.

Given these positive signals, we would welcome contributions to integrate a performant and memory-safe JPEG XL decoder in Chromium. In order to enable it by default in Chromium we would need a commitment to long-term maintenance. With those and our usual launch criteria met, we would ship it in Chrome."
