It doesn’t matter if a supernova dies in Wano or not, they’re not gonna be relevant after Wano anyway
Nahhhh Guys like Capone and bonney are EndGame characters.... bonney is tied too many mysteries that are gonna be relevant at the end and Capone is just a mad man who likes killing people so its not hard to insert him in a future plot and he literally has a cover story right now so he's definitely gonna come back for future shit
Drake is also part of a plot point that could go past wano being the Sword group and Law as I said is connected to the Will of D.
Right now the only supernova with no plot points set up beyond Wano are Kid killer Urouge Hawkins and Apoo. Urouge is somewhat safe because he literally isn't even this arc but still no sign of what he will be doing.... Apoo and Hawkins are the most likely to have their stories end this arc, Apoo is allied with Kaido and is on Kid's kill list and Hawkins is a prime candidate for an ally who dies, that is of he changes sides and then dies... Kid's oby saving grace for being relevant outside this arc is because he has a grudge against Shanks but as we know, the man is always taking L's so his grudges might not matter in the grand scheme of things... And of couse Killer is fucked up so Kid could stop being a pirate for the sake of his fucked men
