it doesn’t actually saw much. As a Catholic I would want to see the Pope clarifying primacy as the Orthodox see it — first among equals, but not “boss man” — and I believe that Pope John Paul II, Benedict and now Francis have shown by their actions with the Eastern Catholic patriarchs that this is what they believe. We just need to put this in writing
I recall reading that one functional aspect of papal primacy would be that some matters could be appealed to Rome as a court of last resort. Not sure just what kind of cases that entails.
