Actually Hickman DID order that according to Leah.
Mind you this was before Children of the Atom. So if that order was still in place-those kids are not mutants or they are mutants-who use to be someone else. We don't know everyone from Miles's Universe that came over.
I'm not so sure about that, but we'll see. I guess I should amend my statement to include new X-characters in general. Antagonists get a pass, seeing as how pretty much every baddie from the past is now in Krakoa.
