Other browser vendors like Microsoft and Brave and Opera could’ve added XL support if they wanted to. It’s not just Google, none of the browser makers want to deal with yet another image format. Only Safari supports the protocol, and even then they don’t support animated images.
IE and pre-Chromium Edge implemented JPEG XR and nobody followed. Safari implemented JPEG 2000 and nobody followed. Implementing an image codec is a lot of work and adds attack surface for hackers, nobody really wants to do that unless they have to.
We have JPEG, we have WebP if you need smaller images than JPEG, and we have AVIF if you want something smaller than PNG for photographs. Unless all of the competition implements JPEG XL again, I don’t think they have any reason to bother. Especially with the whole patent vagueness.
