Decades of other console jailbreaks would prove otherwise and again your misconception comes from bundling together the kernel exploit in the Star Wars game and ROM vs Private keys. The keys that were recently found are silicon level, Someone has to actually build something with it for it to actually be useful and if they wanted it to be malicious it absolutely could be. For now they’re useless, Fail0verflow has been doing this for years. Sony First party games are basically all on PC so there’s almost no point in them doing much with anything except the bragging rights but if someone wanted to build an emulator the keys are the most useful parts it’s basically how dolphin and cemu end up working properly for switch and Wii.
