    Description copied from class: AbstractConfig
    
    Called directly after user configs got parsed (and thus default values got set). This allows to change default values for "secondary defaults" if required.
    
    Overrides:
    
    postProcessParsedConfig in class AbstractConfig
    
    Parameters:
    
    parsedValues - unmodifiable map of current configuration
    
    Returns:
    
    a map of updates that should be applied to the configuration (will be validated to prevent bad updates)
