NuSpock is already too emotional. Adding copious swearing would just turn him into an ill-mannered human with pointed ears.
But ... Trelane, the Squire of Gothos had observed that TOS Spock, too, was ... "ill-mannered." He attributed this trait to Spock's Human half. So, you see that? The apple doesn't fall too far from the tree, NuSpock, Prime Spock, TOS Spock, Fal Tor Pan Spock ... it's all the same.
