Use case: After running a destructive test, which destroyed the partition on it, it might be desirable to be able to format it to make it usable again. Note that this destructive test has not been implemented yet, but maybe I will implement it at some point, it could be faster for huge fake drives.
Another use case could be to limit the size of the new partition to the actual size of the storage device to make it usable.
