At the moment Krakoa tries to avoid an open war at any cost because the mutant species according to Moira is not yet prepared for an all-out war against humanity.
To guarantee their sovereignty against threats their leaders prefer to use economic power and when that fails then use clandestine operations like X-Force or Mystique.
I believe most mutants today would view the cure offensively to the mutant species. But some mutants have powers they consider curses and would do whatever it takes to get rid of them and and have a normal life. For this minority the cure is a hope but in the grand scheme of things their personal will does not matter compared to the weight of survival for the leaders of Krakoa.
Even if some want to be normal and abandon their mutated heritage there is no possibility for Krakoa's leaders to accept a cure as it poses a high level threat to them.
