My argument is based on principle; therefore, it would be in opposition to any such restriction whose purpose is to "ensure" the competency of the candidate; however, it should be noted that there is a difference between such a restriction based on competency, and another based on, for lack of a better term, trustworthiness, e.g. a natural born citizen clause (this is not an argument for, or against the natural born citizen clause, I'm simply outlining the scope of my previous statement).
