Overshadowed by CSS animations for almost all use cases.
Pleasantly surprised.
> I know you all immediately wondered, better compression?. We're already working on that. This worries me. Because presumably, changing the compression algorithm will break backwards compatibility, which means we'll start to see "png" files that aren't actually png files. It'll be like USB-C but for images.
It has fields to say what compression is used. Adding another compression form should be handled by existing software as recognizing it as a valid PNG that they can't decompress. The PNG format is specifically designed to allow software to read the parts they can understand and to leave the parts they cannot. Having an extensible format and electing never to extend it seems pointless.
Yeah, we know. That's terrible.

This proves OP analogy regarding USB-C. Having PNG as some generic container for lossless bitmap compression means fragmentation in libraries, hardware support, etc. The reason being that if the container starts to support too many formats, implementations will start restricting to only the subsets the implementers care about.
For instance, almost nobody fully implements MPEG-4 Part 3; the standard includes dozens of distinct codecs. Most software only targets a few profiles of AAC (specifically, the LC and HE profiles), and MPEG-1 Layer 3 audio. Next to no software bothers with e.g. ALS, TwinVQ, or anything else in the specification. Even libavcodec, if I recall correctly, does not implement encoders for MPEG-4 Part 3 formats like TwinVQ. GP's fear is exactly this -- that PNG ends up as a standard too large to fully implement and people have to manually check which subsets are implemented (or used at all).
PNG is popular with some Commercial Application developers, but the exposure and color problems still look 1980's awful in some use-cases.
Even after spending a few grand on seats for a project, one still gets arrogant 3D clown-ware vendors telling people how they should run their pipeline with PNG hot garbage as input.
People should choose EXR more often, and pick a consistent color standard. PNG does not need yet another awful encoding option. =3

So animated GIFs can be replaced by Animated PNGs with alpha blending with transparent backgrounds and lossless compression! Some nostalgia from 2000s websites can be revived and relived :) Curious if Animated SVGs are also a thing. I remember seeing some Javascript based SVG animations (it was a animated chatbot avatar) - but not sure if there is any standard framework.

This could possibly be used to build full fledged games like pong and breakout :)
