Hi there John Thanks for the clarification. My initial aim was, exactly, to expose those parameters that, as you say, some people don't think should be exposed.
My use case is to allow jobs with different native parameters to be scheduled on our clouster from our Galaxy server. Perhaps a better approach is to use dynamic destinations that try and estimate appropriate values for e.g. hvmem, but at present our users are used to setting such parameters themselves.
