Looking at the various diagrams of FLIP-6, there's quite a few possible
arrangements of the 'building blocks'. I wonder if composition over
inheritance would be preferable as we develop the other modes. Maybe an
approach similar to traits
[example](https://opencredo.com/traits-java-8-default-methods/) to be mixed in
to subclasses of `ClusterEntrypoint`.
