+## Conclusion and Recommendation
 
 With out this feature we would not see the two `EventType`s in the system, so we have improved the discoverablilty of events, for consumption. However while this **opt-in** feature is handy for automatic event creation, we **strongly** recommend to create the actual `EventType` manifests for all events that your application `deployments` produce, as part of your Gitops pipeline, rather than relying on this auto-create feature.
