KM sez: The Boos stay in the Fanonverse, as we've already incorporated them. By excluding them, we basically have to rewrite the entire history of Matt (no Boo) as well as rename other Boo-related characters. So the Boos stay. Only difference is that they won't have no prior link to anything Mario-related. They're part of our Fanonverse now, so they'll simply be considered a subspecies of regular ghosts.
