I have been told that we need 2 people to do code review, in a team of 3 people, and we can just “ask a member from another team who works on the same product”.

I have been told that we need 2 people to do code review, in a team of 3 people, and we can just “ask a member from another team who works on the same product”. We were told that outsiders can act as external bar raisers who will comment on “overall flow and code quality”. Sounds like glorified and highly opinionated linters whom will just gatekeep progress because they “don’t get it”.
