When it was removed, no other browser supported JPEG XL, and no other browser had expressed an intent to do it. The last thing the web needs is more image formats with limited support. (Could they even have supported it consistently across platforms due to the iOS limitation on all browsers needing to be implemented on WebKit?)
Apple implementing JPEG XL in Safari changes that. Now it's a format with a real chance of being supported across the whole ecosystem.
