In my experience, the problem you’re pointing out is a non-problem. I’ve never done an in person code review in my life that didn’t take place in an interview context. Yet, somehow none of my mistakes in writing code (and there have been many) have never become “a public albatross stuck around [my] neck.”

Is this a thing you’ve seen or just something you’re afraid might happen? If the former, I would say that’s an unhealthy work environment. If the latter, then why point it out?
