Would it be possible to add an option so that, in non-interactive mode when a parameter is missing, an exception is thrown rather than the default copied from the .dist file?

Use-case: The parameter handler is great for our developers when they are working. But our deployments are automated. Usually the defaults given in .dist are not suitable for CI, QA or production environments. I want our build process to fail when keys are missing from our parameters file, and not copy the defaults.
