I think this is an example of Fr. John Romanides dictum that 'with the exception of well-known differences' Orthodox Christianity has more in common with Orthodox Judaism than the Christian confessions which arose in the Augustinian West.
Whenever I hear Orthodox Christians discussing the canons, I can't help but think of the Isaac Bashevis Singer story in which after the one old Jew convinces his friend that the exception for 'the days of persecution' to lighting a menorah publicly means 'the days and lands of persecution', then returns to find that his friend has lit all eight candles. "What is this?" he asks. "School of Shemai" "No one has followed the School of Shemai for a 1000 years" "Yes, and they were all wrong!" (Oddly, the Jews have a feast for the miracle which accompanied the Maccabean revolt, while the event is recorded in Scriptures only we Christians keep in our canon.)
Merely because Catholics have attempted to codify Canon law does not mean that the entirety of it is not still hotly disputed whenever someone attempts to apply it. For example, see the 30 year long dispute with the SSPX and Rome over application of canonical sanctions, supression of the society, presumption of ability to incardinate, etc., etc. Or look at any discussion over annulments. Or interference by Bishops in parishes with abnormal canonical underpinnings in their foundation and control.
