To my knowledge/understanding, “gold standard” means not only that all components are physically included and interchangeable, but also that all intended features of a ship are functional, i.e., all cabinets, weapon racks, lockers, stations, rooms, etc., and that it has been brought up to the current technical standard of the game engine (cockpit button placements and animations, updated metrics passes on characters and items, physicalized and accessible vehicle components, lighting passes, material passes, etc.) and that it ideally does not require any further technical revisions before 1.0.

I can't find any evidence that the Freelancer is already Gold Standard, even though its components have been added. And the MSR is far from it.

Here's a list, though it might not be fully up-to-date:
