It could be an issue if an eshop title is needed (maybe for a save exploit of some kind) to run the hack? Let's say it's released, Nintendo quickly releases an update fixing the vulnerability, you get the news too late and try to get the hack for yourself. You have to update to use the eshop to buy the needed game, no hack for you. Unless the game was already owned of course.Why is a system update an issue if the 3DS is hacked?
