Is it a good idea to start replace PNGs in my website by WebP now that support is there, or should I wait for AVIF to be more widely deployed? AVIF is better than WebP and is now supported with the last version of Firefox, but still isn't supported by Safari. Obviously, I'm going to fallback to PNG anyway using the <picture> element.
