Once a WISEid generated it should never be invalid
Districts should not need to delete or update a WISEid that is merged with other records. Both IDs should remain valid so that school staff are no longer concerned with getting lists of WISEids to change from DPI.
This would not eliminate all manual updates as splitting an improperly matched WISEid would still require at least one district to update its records. However the local_row_key could be used to assist in those scenarios.
