So AVIF now work with every browser.
So I like to see it supported but with an important step.
HDR meta data should not be deleted when responsive images are created, it should be a toggle “keep hdr metadata” or so.
I see alot of auto converters destroying essential parts of the original image for example alot of CMS ignoring alpha and/or the animation inside webp images.
And I think HDR is something that could be overlooked 🙂
