This copy of the plan is used only for plan monitoring from the UI (and from Java APIs) and is still not used for scheduling purposes that continue to work using the Symphony file to assure consistency between Master and agents.
This change has tremendously improved the scalability of the UI with performance test that has shown almost no performance degradation increasing the number of users monitoring the plan.
For end users or cloud customers this is completely transparent, but for IWS Administrators that are managing an on-premise environment this introduces new components in the product architecture that need to be understood, monitored and eventually managed and recovered.
