I think your carbonara would be accepted.
Italian food is fairly simple, so yes attention to detail and produce quality are key. But even in Italy quality is dropping.
The best Pizza I ever ate was from an Albanian pizzaiolo. Within Italy we have debates over what pizza style is the best. What a Roman sees as a quality a guy from Napoli will perceive as a mistake.
The truth is: Tuscan pizza is the best! 🤣🤣🤣
