That's the whole philosophy of spaceX and explicitly starship though, right? I mean they literally lauched a water tank up 100 feet and hovered it back down as a demo, then immediately scrapped it and proceeded to build 27 Starships, when not a single one has reached orbit.

building the header tanks in the first place, and testing them is the interation style. If the starship blows up, the header tanks are the least of your worries.
