I think that it has roamed around in people's minds, but I think that in this world it's just not practical. The concept of dual citizenship and triple citizenship sometimes can work both for and against people.
Certainly, for one of the cases that was recently in Iran, the fact that the person involved had triple citizenship allowed triangulation. I think that most consular officers and the people who deal with them understand that this is just the way of the world. It's not going to get easier.
