Correct… I have not submitted a PR yet…
Returns:
str, decimal, boolean, None, or dict: The ``configuration`` key value
will be returned. Since None is a valid value for a key, when the key,
Item or namespace does not exist, this function will return an empty
dictionary.
When/if you do, core.metadata.get_key_value will be able to handle it, since it can differentiate between null and undefined metadata key values.
