But it’s a big deal to have that field be named. Like you say, literally anything can be put in the unnamed metadata fields, giving them no weight. PNG even has arbitrary metadata fields and that hasn’t translated to anything remotely resembling proper dpi support there.

Correct, which is why I said realistically this is all in the hands of Adobe. They could support DPI on PNG tomorrow if they wanted to, and their metadata label would become a de-facto standard overnight.
