I think this is part of the JSON spec. See http://json.org/object.gif for example.
Also, this is already documented in the json.dumps() documentation:
> Keys in key/value pairs of JSON are always of the type str. When a
> dictionary is converted into JSON, all the keys of the dictionary are
> coerced to strings.
