      When trying to use the @overload pattern for type stubs, it seems that the type system is resolving CodecOptions[_CodecDocumentType] as Any in the second signature, which supersedes Optional[CodecOptions[_CodecDocumentType]] :

      motor/core.pyi:264: error: Overloaded function signature 3 will never be matched: signature 2's parameter type(s) are the same or broader [misc] async def command(

      The full signatures:

      @overload
async def command(
    self,
    conn: Connection,
    command: Union[str, MutableMapping[str, Any]],
    value: int = 1,
    check: bool = True,
    allowable_errors: Optional[Sequence[Union[str, int]]] = None,
    read_preference: Optional[_ServerMode] = ReadPreference.PRIMARY,
    codec_options: CodecOptions[Dict[str, Any]] = DEFAULT_CODEC_OPTIONS,
    write_concern: Optional[WriteConcern] = None,
    parse_write_concern_error: bool = False,
    session: Optional[AgnosticClientSession] = None,
    **kwargs: Any,
