Except those inconsistencies are coming from mutant characters in non x books. Stuff characters like Wolverine and Xavier say in non x books don't gel with what other actual X books say. It feels like every writer got different notes on what Krakoa is
Back to my earlier point, it does feel a bit inconsistent (if the intended message is "no we aren't removing characters backgrounds and replacing them with 'Krakoan' now") it doesn't feel consistent across the board with characters like Nightcrawler giving up Catholicism and them cremating a prominent Jewish hero
