      Note that at the moment this function will only find exact duplicate
      Registry key paths.
  
      Args:
        filename (str): name of the artifacts definition file.
        artifact_definition (ArtifactDefinition): artifact definition.
        source (SourceType): source definition.
  
      Returns:
        bool: True if the Registry key paths defined by the source type
            are used in other artifacts.
