Sure, but the rare catastrophic failure issue is not why the Spaceshuttle is widely considered an engineering failure. The real issue with it was that the re-usability of it turned out to be a huge money sink. Spaceship might face a similar fate with those heat-tiles.
I’d much rather be on a spacecraft that wore out too soon than one that catastrophically failed
