Elaborate please. PI on its own is just an insurance API for banking and similar apps to ensure that they can do secure compute on the device. It can also be used to check if the device that the app is running on is a genuine Android device, since no VMs or custom ROMs can pass hardware integrity.
What sense is does it make to certify an insecure device that may be subject to all kinds of remote exploits and elevated code execution as 'unmodified'. The argument of the banks is: the device is insecure (even with the latest patches). We all know the whole compliance is a bit more complex, so it might make sense on that level...
