For this particular batch of backups I wanted to avoid encryption because I want my kids to be able to decode the seeds in case I'm no longer around. The backups will be stored in a safe, to which my kids will receive the combination upon my demise.
in that case you might want to also include a clue of what that backup is and also a walk-through of how to convert it back to something they can import in a wallet (ie seed) because your method is not a known method that is commonly used and that can impose complications.
