@darek_kay Yea I think it will just be handled in the background by CDNs. They can check if the user agent requesting the image can support AVIF or WEBP and then serve the appropriate version. So complicated.

@darek_kay This is great and to the point. Thank you for this!

And then I started thinking about providing fallback image formats and responsive images at different sizes using sizes and srcset and my brain exploded thinking about that markup.
