Maybe, maybe not; but that has nothing to do with Constitutional requirements for Presidential eligibility. I have no idea why you even brought it up.
Because guaranteed they are going to look at it if they ever take this case. The laws of citizenship that most people in America at the time the constitution was written would have been familiar with are certainly something worth considering.
And with the likelihood they would practice a little bit of ends based jurisprudence, they are definitely going to consider the laws which most help them achieve their ends. Its all well and good that yall think Vattel is the intended definition, but with no explicit evidence of it, I can’t see them using it.

True .. Wong Kim Ark wasn’t a candidate for potus;
therefore, that consideration was never a basis for
the ruling for his citizenship issue.
