Using update can have unintended consequences such as setting empty values of fields that were nil on the server. This happens for the evaluationInterval field where if it wasn't set, the update adds an empty map, which triggers the spec-sync to remove the nil map. This unnecessary spec-sync update causes the status update to fail later on in the ConfigurationPolicy processing.
Additionally, when a finalizer can't be added or removed, the evaluation stops and would be retried on the next run. This is a safer approach.
