To be fair, bioctl talks to block I/O devices (i.e. nothing to do with filesystems). So it is hardly surprising that this can happen considering that fact. Do you want "rm -rf /" to hold your hand also? You could also blow away a disk with "dd" if you're not careful - should that try and preempt you from making a mistake? I know that doesn't help you, but I can imagine that's the rationale. If you want to shoot yourself in the foot, that's just fine.
