That is a really good point; France still might run into problems later (in the 1560's and after) if the crown still moves toward toleration of protestants; and if France compounds this by supporting protestants abroad to weaken Spain, that could complicate things for the Vatican even further. But that's down the line, and not really enough to guarantee another "nationalist" split of the remaining Catholic Church.The Concordat of Bologna of 1516 made that largely irrelevant. Within France, the King was the de facto head of the church.
