> So I guess I wonder if it's that the Chrome team had set the bar high, that they hadn't expected Apple to support JXL at the time they made the call, or something else.

I think it’s something else.

I’ve read enough CSS Working Group (and other groups) meeting minutes to know when Google wants to implement something, that’s what they do, often when the WebKit and Mozilla teams don’t agree.

Whatever happened for Google to reverse their position on JPEG XL, I don’t believe it has anything to do with the technical merits of the format or whether Apple had planned to implement it.
