Here's a fun one @gruber — I am not a Mail user for the most part, but wanted to check out the new categories feature on macOS.
I turned them on and this was the AI suggested primary email: a phishing scam for Netflix.
I don't know if there's a way to prompt the suggestion again or not (again, not an avid mail user), but as you can see from the sender info this should've been something that hit Junk and definitely not prioritized
