Why Not Arakko?

In Uncanny X-Men 700 (or the end of Fall of X) after Krakoa dissapeared, why didn’t all the Krakoan mutants move to Arakko? I know that Aarako just got through a civil war, but it seems like a safer option given that there’s about 2 million mutants up there (I think?) and a whole government and mutant society. And why isn’t Storm the Regent of Arakko anymore? Don’t get me wrong, I like the new war of X- Men a lot, but I don’t get why everyone didn’t just move to Arakko.
