I think they would only show up in the case where the deleted account is from another trusted domain. When we delete user and computer accounts in the same domain as the DGG, we never end up with unresolved SIDs.
During our AD migration, I did find a few related to broken down trusts but I rewrote the procedure to delete the accounts before destroying the trusts.
