Google Pagespeed: recommendation WebP, JPEG XR and JPEG2000

I made a check of our website with Google Pagespeed. Google give the recommendation to use one of this image formats: WebP, JPEG XR and JPEG2000.

Do you support this? And is this meaningful?

WebP = 77% global coverage. IOS 12 nope.

JPEG2000 = 12% global coverage IOS 12 nope. Chrome nope

JPEG XR 5.2% IOS 12 nope. Chrome nope

So the answer is “don’t pay attention to everything Google says”.
