Does having a Nintendo-signed IOS16 (IOS16-64-v257-prod.wad) mean that we'll always be able to use it to install WADs, using the IOS16 version of WADmanager? No matter what holes they patch, we'll always be able to install IOS16 using WADmanager and work from there (f.ex. install cIOS cIOS_249-rev6_rr.wad), right?
