Is it possible that in the 20th century, a pope would have stepped down and started a tradition of popes stepping down before they died? What if there were two pope emeriti alive at once? Would this have major consequences for the Catholic Church? For example, perhaps in the 40s a pope emeritus could have openly disagreed with the current pope on whether to speak out against the holocaust, perhaps? What are your thoughts? And might OTL's Benedict XVI be starting a precedent that could have unintended consequences?
