Compared to something like JPEG XL? [PNG] is hands down worse in virtually all metrics.
Until we circle back to “Jpeg XL isn’t backwards compatible with existing JPEG renderers. If it was, it’d be a winner.”
APNG, as an example, is backwards compatible with PNG.
If JPEG-XL rendered a tiny fallback JPEG (think quality 0 or even more compression) in browsers that don’t support JPEG-XL, then sites could use it without having to include a fallback option themselves.
Why are you using PNG when it’s not backwards compatible with gif? They don’t even render a small low quality gif when a browser which doesn’t support it tries to load it.

Are you seriously asking why a commonly supported 27 year old format doesn’t need a fallback, but a 2 year old format does?
