Some cool innovation! Love it.
Just recently, SpaceX’s Falcon 9 launches passed the 500 mark, with 400+ booster landings for reuse. I suspect that these core boosters may begin to see more work, with heavier loads and bigger fairings, if the Starship develop continues to stall. OTOH, just because they run a little late doesn’t mean they don’t get where they’re going. :^)
