Why is that one implementation detail notable? Is it also notable that Starship's main engines are unused at launch? I realize re-lighitng main engines is novel but it isn't unique and even if it was that doesn't make the up-thread claims any less inaccurate. Shuttle was a reusable orbital vehicle with multi-day endurance capable of hypersonic reentry. Falcon 9 is not that.
