This would be a very Last resort. Aside from infection risks you are going to cause barotrauma which we know worsens mortality. In mass casualty or trauma events the pt needs stabilization and ventilation but the issue is usually not lung compliance, so this is somewhat better use. In ARDS lungs are not as compliant. Imagine two patients where one has less compliant lungs and you use one ventilator, how are you going to prevent the barotrauma, maybe try to match lung compliance? The paper you link also says this would be potentially useful in mass disaster for a limited time.
