Inject config into a KubernetesDependentResource

I'm trying to inject some dependencies into my KubernetesDependentResource.
For dependent resources I usually do this by implementing DependentResourceConfigurator:

// Dependent resource
public class MyDependentResource
        extends PerResourcePollingDependentResource<MyDependent, MyPrimary>
        implements DependentResourceConfigurator<MyConfig> {

    @Override
    public void configureWith(MyConfig config) {
        this.dependency1 = config.dependency1();
    }
}

// Startup code
Operator operator = new Operator();
        operator.register(reconciler, r -> r.replaceNamedDependentResourceConfig(MyDependentResource.NAME, new MyConfig(/*...*/)));

But KubernetesDependentResource already implements DependentResourceConfigurator, so I can't configure my own config.

Currently working around this issue by using a singleton pattern.
I inject the dependencies into the singleton and initialise it before the dependent resource reconciler is created.
The dependent resource reconciler then fetches its dependencies from the singleton.

Is there a different way to do this?
