> When NiFi Registry was created, it was created as a sub-project. There were 
> good reasons for this. The release cadence wasn't yet known, the smaller 
> codebase would make things less intimidating for developers who were newer to 
> the community, etc.
> However, we've seen over the last few years that the cons have been much 
> weightier than the pros. There has been a lot of code duplication. Registry 
> often lags in features behind NiFi. There's significantly more maintenance 
> because of this code duplication.
> There's also the problem of circular dependencies. NiFi depends on registry, 
> but often a new feature is added to NiFi. We want Registry's data model to 
> support this. So we update registry's data model. But then registry must be 
> released before NiFi can be updated to use the new data model and map into 
> it. 
> Also, the VersionedProcessGroup, etc. that exist in the registry data model 
> have become integral to NiFi.
> We need to merge these two codebases. This will result in a single release 
> that encompasses both projects. This is much easier for the Release Manager 
> as well as the community who votes on it. The data model will be dramatically 
> easier to update. Registry will benefit from third-party dependency updates 
> to avoid potential CVE's, etc. by improving the maintainability.
