If it gets a new Earth designation in, as well as a clarification if it's indeed a new reality, a new page should be created for it and Earth-616 would become an alias rather than it's official designation. AnnabellRice explained it pretty well in the other discussion, but I think the only new characters who would not be "born" into this new reality that only appeared recently are the ones who are shown to have existed before the events in Secret Wars through flashbacks.
