Uh, I think that having such written clarification would not be healthy for the Church. I’d limit myself on trusting Holy Spirit to lead the Pope as he had until now, to preserve him from error. If Pope saw any problems going on in Eastern Churches and had to wait until something happened to resolve it, it would hurt the Church.
We have all means of communications nowadays- unlike in 1st millennium, where it was not humanly possible for Pope to resolve everything even if absolutely necessary. I think using the infallibility of Pope granted to him by Holy Spirit to enrich entire Church and preserve it would be much more optimal. Dignity is important, but not more important than remaining clean from heresies and schisms. I would however be able to imagine a scenario where Universal Jurisdiction is limited to things concerning faith and morals. Appeals could be used for practical issues like jurisdiction etc.
