> Why continue messing with PNG at all? Because if you can figure out how to squeeze new features into PNG in a backwards compatible way, it's instantly compatible with all browsers, OS's, engines, etc. This is valuable

What a brilliant paragraph. I wish this developer all the success in the world.

The backwards compatibility is okay, but the author should also plan a more optimal replacement encoding that ditches the legacy compatibility, and require new implementations to support both.

Otherwise there is no way to sunset the hacks.

They should just make a new format. It's not clear if this is an improvement over AVIF either.

We've already got JPEG-XL as a good replacement format, but some feel that jeopardizing its adoption is a sensible cause.
