So what? At least only my snazzy file manager and media player get access to /sdcard - they still can't access other application's data to dump my browser credentials or modify those applications binaries to behave differently, the most harm they can do is delete my downloaded TV and pictures. Only my backup tool gets root and can access other application's data - random trash games I download or even if I were to install them from pirated sources are unable to do that. It's a vast improvement at the very least, even if not a perfect one.
