That doesn't really apply here. The dynamics of stage separation on Starship are orders of magnitude more complex than anything used on any previous rocket. If you want to look at what failure looks like for a super large rocket compare it to the failed Soviet N1. This flight demonstrated better performance in a single test flight than every N1 test flight over years. The N1 suffered catastrophic failure after catastrophic failure. Starship was pushed way past its design tolerance and showed its design is technically sound. Failure is unavoidable, the Saturn V almost failed its first test flight way earlier than Starship did here.
