Nothing has ever been or will ever be perfect revision 1. That doesn’t mean it shouldn’t happen. The real world will always be where flaws get light shined on them. To your point, no one is still using Model T’s, flying Wright Flyers, or still living with a Jarvik 7 heart implant (note the 7 implying incremental progress). Further, the entire history of space exploration is built on learning from failures and explosions.
