Alphinaud and Alisaie also can't die. They ran the Binding Coils of Bahamut content.

When you start taking apart what characters have vital roles in additional content, you start to see who can't die.
They're very happy to time capsule that stuff, honestly; they have been ever since basically 2.55, when Culinarian's storyline suddenly got really awkward. 'This character died in the MSQ but still turns up for stories' is definitely more extreme than any example we've got, but they've definitely had similar weirdness. I think the most exceptional is actually Arenvald turning up in the Summoner level 80 quest.

Again, I don't think those characters will die, because they're fundamentally pretty big parts of the game and the way they write stories, and also the developers just don't really want to kill them anyway. But I'm not sure this is the evidence you think it is.
