If this "new" universe is a mash up of previous realities, then all of its inhabitants (except those born after the mash up) are native of their respective universes, even if they didn't appear in comics until now. Considering so far only a few characters will transition from, for example, Earth-1610 and Earth-807128 to Earth-616, it wouldn't be necessary to label them from another universe unless noted.

It's also worth mentioning Brevoort's comment on "Universe 8," Ewing mentioned said name would be clarified in his books (probably Contest of Champions).

I mentioned a few minutes ago to take Brevoort's comment with a grain of salt. That's because this wouldn't be the first time somebody like him (or Brevoort himself) commented on something regarding this whole thing about realities that turned out to be untrue. Like his (and Marvel's) comments on Age of Ultron.
