I am not entirely sure how the unbound logic works. But it seems like this might be happening
because the trust anchor that is revoked (key tag 41992) comes in via DLV. But yes, technically,
this should be a ServFail.
I trust you will add logic to look up the DLV record before allowing one to finish a KSK rollover :)
