Another option could be to switch from a polymorphic variant to a simple type, e.g.: type input_transport = | None | VDDK of vddk_options | SSH So it will remove the extra vddk_options parameters in most functions where input_transport is passed, and easily support more options for future transports. The rest of the changes seem fine. -- Pino Toscano
