If there is a kernel bug that corrupts the superblock, then we should fix the bug, not put in lots of validation to see if the bug has hit.. And if a superblock did get corrupted, then fixing it is a userspace (mdadm) issue, not kernel. Or maybe I'm not understanding what problem you are trying to solve.
