It is just a spec on something widely implemented already.

Assuming Next gen PNG will still require new decoder. They could just call it PNG2.

JPEG-XL already provides everything most people asked for a lossless codec. If there are any problems it is its encoding and decoding speed and resources.

Current champion of Lossless image codec is HALIC. https://news.ycombinator.com/item?id=38990568

When it comes to metadata, an implementation not being widely implemented (yet) is not that big a problem. Select tools will do for meta, so this is an advancement for PNG.
