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
