None of this means nobody ever reviews code. There are absolutely changes where I want another experienced human looking. An example would be a fundamental architectural change. Assuming we did a design session as a wider team, we might want to review the code as a team or agree it was implemented right, or discuss if we want to change anything. Other examples could be something crossing a sensitive security boundary, a change with a huge blast radius, an unfamiliar part of a critical system or simply something where the team says, “I’m not confident about this.”

Review By Exception, not by norm.
