def normalize_empty_parser_config(cls, v: Any) -> Any:
        """
        Normalizes empty parser configuration by converting empty dictionaries to None.

        This validator ensures consistent handling of empty parser configurations across
        the application by converting empty dicts to None values.

        Args:
            v (Any): Raw input value for the parser config field

        Returns:
            Any: Returns None if input is an empty dict, otherwise returns the original value

        Example:
            >>> normalize_empty_parser_config({})
            None

            >>> normalize_empty_parser_config({"key": "value"})
            {"key": "value"}
