( …I’ll be fair and say that ectobiological incest is probably the least of some shippers concerns and leave it at that aha… but Hussie sent a tweet that “canonized” all ships in an act of “magnanimity”. So all ships, somewhere in the universe, are real. The degree of realness’s is up to you though lol )

Well given the complexity of the kids biological existence, it would be hard to shift it all out. 

But it is nice of Hussie to give leeway for the fans on their ships. I don’t think I have seen any creator (other than for Rick&Morty and TAZ) where they actively say “yeah this is my story, but i’m sure there’s another universe where your idea is right, so go ahead and enjoy yourself.” Those kinds of people are pretty cool.
