While auditing/working on migration stuff, Alexander Popiak caught an error in one of our Democracy migrations on Kusama. There are still some old storage items under Democracy.VoteOf. I opened this motion to kill the storage prefix for this item via a Root call to System pallet.
Anyone can verify the existing storage items by querying Kusama under the prefix: 0xf2794c22e353e9a839f12faab03a911b02a7afbcd5cd4ad2c68bbc63279ae52e
This is equal to xxhash("Democracy") + xxhash("VoteOf") which you can see in the democracy pallet is not used. It was a typo in our migration code that would normally have cleaned this storage up.
