Alas, EXIF's metadata is of dubious quality and utility, and PNG's is hardly used at all.
So, nice-to-have-maybe. Not sure I even want to devote the UI space to this. I guess it's neat to show other photographers what settings you used, etc. (Oh, and would sometimes head off "what did you use to make this" questions...)
PNG has some chunks. EXIF is also a thing.
