You can do this with a very short subclass of the JSONEncoder:

class MyJSONEncoder(JSONEncoder):  def default(self, obj):  return obj.json()  # with a useful failure message I don't think it needs to be built into the default encoder.

Yes, but you need to customize in that case the encoding process and own it.

Having a builtin recognition of json would allow you to pass your objects to be serialized to any third party code that uses a plain json.dumps.

For instance, some web kits out there will automatically serialize your objects into json strings when you want to do json responses. e.g. it becomes a builtin adapter
