Kobo doesn't follow this - and the interesting thing is: SDs from defective Kobos work great again after they have been repartitioned according to the above guidelines.

Have you ever looked at a Kobo µSD card's partitioning scheme? You would notice that there is space at the start of the card that is not partitioned. Much like on your SSD or HDD where the boot block is not part of the partitioned space though information on the partitioned space is stored there.

And once again, the spare blocks are not visible as part of the storage space. The on-board controller takes care the logical to physical translation to spread the writes across the entire erase pool in hopes of preventing premature failure.
