There were a LOT of people using Gateway to downgrade back when it was the only way. And yet there are no confirmed bricks.1. Gateway Downgrading can cause bricks the process isnt perfect its just not noticeable because the small amount of people using gateway vs the thousands using Plail downgrader
1.1 also take into account most users frequent temp/reddit for help with downgrading (gateway users are less likely too due to people buying flashcarts like back in DS days)
1.2 Regardless of them having low amount of reported bricks, at least people dont brick using modifed CFW or another devs CFW using code from each other
Aka gatewaybricking unknowing users who either had clones, modifed launchers for region free or were just plain unlucky
