There were two different animated PNG extensions, MNG and APNG. Neither of them ever really caught on. I guess they're hoping to do better by baking it into the core spec.
APNG is what they're using in v3, so all many libraries need to do* is update that code for HDR.
* surely that's easy, right?
I mean, on a Linux system that's not riddled with flatpak / snap / ... You'd basically only need to update libpng and you'd be good.
