I think Jean's approaching it with a mindset close to this. Mutant's aren't a unified people but the world treats them essentially all the same. They were becoming numerous enough to form their own styles and culture in Morrison's run before they regressed everything, and as Jean pointed out gathering a bunch of mutants together nowadays is just and invitation for those that would to come and murder them all.
It's interesting that Jean got both Wakanda and Atlantis to back her in this idea, and now it's even more complicated as Namor will be seen as harboring a fugitive until Jean's proven innocent.
I don't know, but the Wakandan ambassador seemed pretty chill with Namor in the room.
