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

I'm using png in a computer vision image annotation tool[0]. The idea is to store the class labels directly in the image [dispensing with the side car text files], taking advantage of the beautiful png metadata capabilities. The next step is to build a specialized extension of the format for this kind of task.
