Mozilla indicates that they are willing to consider it given various prerequisite. GP translates that to being “more than willing to adopt it”. That is very much not a normal interpretation.
> To address this concern, the team at Google has agreed to apply their subject matter expertise to build a safe, performant, compact, and compatible JPEG-XL decoder in Rust, and integrate this decoder into Firefox. If they successfully contribute an implementation that satisfies these properties and meets our normal production requirements, we would ship it.
