Do you mean the users of the browsers not benefitting, or specific Google employees/stakeholders?
They always abandon shit like this.
Google apparently wanted to be one of the "cool kids" supporting AVIF. When they removed the JPEG XL code from Chrome, they created the excuse that there was little demand for it, along with some other disingenuous talking points that didn't quite make sense. Ironically the project that ended up becoming JPEG XL was started by Google employees in Switzerland.
Anyway, I’m glad Google is supporting JPEG XL now. I wanted to use JPEG XL files for a project I started a month ago, but it was a non-starter with global usage under 20% at the time.
Another giant codec is only a huge risk if you run the decoder in the renderer process, which they say in the linked thread they do, but I don't see a sane reason why.
I'm sure if they asked the secret Gemini 4.0 AGI to use their existing very good sandbox to throw all the decoders in their own process and only share the image buffers, it could do it in a few hours.
Removed because trillion dollar advertising company don't bother, which also happens to be the browser vendor monopoly.
How many man-hour effort does it take to create jxl-rs ?
