No, you're got upvoted by me. XML is great and has all kinds of well-tested tools - query language, schema validation, namespaces, etc.! Not sure why people think it's worse than JSON, TOML or the likes. Less readable? Not really. Plus, more people know HTML than JSON and so it should be less easy to learn than even JSON for people who already know HTML. Maybe the only improvement would be to make it more relaxed like HTML5.
