This CLI arg was deprecated in Newton in favour of using the param in a environment file. The CLI argument is still present but is no longer the recommended approach and will be removed in the future. It was deprecated as it maps directly to a Heat parameter and this it makes more sense to store it in an environment file with the other Heat parmeters in the deployment.
