It depends if you consider Ace’s novel canon. There he got gifted CoC like candy, and if bofh Luffy and Ace randomly get CoC/ADVCoC there’s no reason for it not to have it.
Same with Blackbeard, Akainu, Imo if they can fight and the King of Elbaf if he fights, at this point, CoC has been fleshed out, so Oda will use it the most.
