One possible problem I can see here is to do with removal of RAID. Think of a RAID-1 array (2 or more disks containing identical data). The partition can be validly identified as an ext2 filesystem. But wait, it has a RAID superblock at the end.
How do we know if this superblock is current or not? After all, a mke2fs on the device won't remove it. Yes, you could fill the partition with zeros and start again, or you could just change the partition ID.
