In many environments that depends on more than just code review, e.g. CI.

Sure, it depends more than code review, but the code review is still a boolean flag, i.e. BOOLEAN getsMerged = codeReview && passesCI && passesTests....

Unless you're implying codeReview is a score and a low code review score can be offset by higher scores elsewhere eg. passes more tests?????
