I don't know. We haven't probed what zero-G manufacturing might be capable of. One of the amazing properties of a near-perfect vacuum is that there are near zero contaminants. Being able to more accurately control reactions might yield breakthroughs in room-temp superconductors or metallurgy. I could imagine there's some low-hanging fruit too since we're just starting to probe the possibilities. That all said, it's therefor possible that the things that make these supposed craft unique might be defined by their requirement to have been manufactured in a zero-G vacuum.
