Oh many people have tried adding namespaces to json. It's just that these people and their solutions are consistently ignored by most developers. If you consider that Json came out of the javascript world where people tend to prefer to not specify a lot of types, it's perfectly obvious that they would probably not want or need any namespaces. Never was a thing in Json. And good on Douglas for keeping Json simple. The comment thing is annoying indeed. Using a good parser, you can usually configure it to not freak out over stuff like that. But sadly that is not very common. Elasticsearch is a positive exception. It will happily accept comments.
