I agree with your premise, but not with your digression. I still read the code reviews of my team’s experts closely because: 1) I might learn something. If they are experts in the domain, they almost certainly know things I don’t. 2) Even experts have blind spots and make mistakes.

If I trust my teammate I default to “accept to unblock” and leave some questions in comments.

If my concerns are valid, they can fix it before landing. I also trust them to request a fresh review if that leads to major changes.

If I misunderstood, they can educate me in their reply and land it without further delay.
