Not sure what you mean. They have to have this stuff on each Starship anyways. And they need to learn how to build that stuff. Its already built into the next Starship. And that ship (in fact the next 4) have no other reason to exist other then testing these things. The ship is the payload. The testing is inside of the tanks of the ship. Moving fuel around inside the ship. There is no extra expensive payload in addition to the ship.
