Apparently only IE and Edge support JPEG XR, so the format not being used on the web will happen on its own anyway.

Well... With Edge phasing to Blink noone will support JPEG XR

The Edge team could still decide to integrate their JPEG XR implementation into Blink. That would mean Chrome would gain support for JPEG XR.

What makes you think the changes would be accepted into mainline?

They don't have to be; Microsoft could maintain that as a separate fork/add-in to Blink. In theory it sounds like it should be highly modular, so that shouldn't be a huge ongoing maintenance burden.

I don't know why they wouldn't just switch over to WebP in preference to that, though. It's better to have fewer of these formats around and the simplest thing to do is use the one that already has support.

Note that parent said "Chrome would gain support for JPEG XR", which I believe is what 05 is replying to.

Could yes, probably not. Because very very few is using it.
