@CliftonR The big red flag I see here is the SV mindset of 'move fast and break things' and 'rapid iterative design' applied to launchers. I have worked in both industries. This method works for s/w because you need to solve problems only once - even if the code is a big kludge.
But it doesn't map well to rocketry where unlike s/w, safety margins are razor thin and nothing is repeatable. It may work someday, but I will be worried about the technical debt waiting to rear its ugly head.
