Where does your faith that other /bin/sh implementations (dash, busybox, etc.) are less buggy comes from? On the contrary, bash being the most used, beaten, patched, and studied of them all has plenty of arguments to claim to be the most secure /bin/sh implementation around. You just don't know about those other guys bugs. No reason to believe hackers don't know about them either.
