I never thought they'd use this show or Wanda's powers to create mutants in the MCU and it just seems like a bad idea to me. To me, having mutants "created" by a specific person or incident or source would make them more like Inhumans. One of the big points of mutants is that they are a part of human evolution. Remove that and you miss a core issue of mutants as any kind of allegory for the differences and varieties of people within the human race.
