JPEG XR is only supported by IE (since version 2011) and Edge before the switch to Blink/Chromium. Webp is supported by everyone except Safari and IE, but Safari and mobile Safari have about 15-20% combined market share.

New formats are basically only relevant if they get blessed by Google/Chrome, and even then you often need fallbacks for a long time.

The thing that held us back before was legacy tools and browsers. Not anymore.

If we can agree on a standard (hard, I know) we can star using it pretty quickly.
