That's not what the x- prefix is supposed to mean. If we have an internal constraint that we mustn't delete the option in order to support some other must-be-stable interface (eg migration of some machines) we can document that in a comment, but that doesn't mean that we should document to users that direct use of an x-prefix option is supported as a stable interface. Alternatively, if the option is really stable for direct use by users then we should commit to making it so by removing the x-. thanks -- PMM
