Most changes are code refactoring, but I noticed that some Events originally sent to the Cluster CR are now being sent to the Component CR. This could introduce breaking changes or make it difficult to observe or debug the cluster's status. Alternatively, we could introduce an event aggregator to aggregate Component events into Cluster events.
