Yeah, I like the sentiment here, but I wouldn't pass review on a piece of code that had the "@generated" tag on it to absolve either the author or me as the reviewer of actually understanding what it does.

At the end of the day, whether you copy-pasted the code from StackOverflow, let Copilot generate it or M-X-Butterfly'd it in yourself doesn't make a difference as you still need to understand thoroughly what it does.
