That’s a bit too extreme to me (and already covered by unit tests). Code reviews are good mostly for asking questions, not dictating changes.

I do agree but too often they turn into "well I would do it this way".

If it is some very big and very critical system then yes, code reviews can be beneficial compared to the alternative. But for systems that are innovative and rapidly going through iterations as it is, it's better to judge coverage of test cases (and adequate performance but not optimal)
