Please don’t. If you need something like json but with comments, then use YAML or TOML. Those formats are designed to be human-readable by default, json is better suited for interchanging information between different pieces of software. And if you really need comments inside JSON, then find a parser that supports // or /* */ syntax.

Yes, it’s a field. Specifically, a field containing human-readable information about what is going on in adjacent fields, much like a comment. I see no issue with putting such information in a json file.
As for “you don’t comment by putting information in variables”: In Python, your objects have the __doc__ attribute, which is specifically used for this purpose.
