-
-- This feature is implemented on top of the Fabric8 client informers, using additional caches in `InformerEventSource`,
-  so it is safe to use `context.getSecondaryResources(..)` or `InformerEventSource.get(ResourceID)`methods. Listing

-  underlying informer cache, thus bypassing the additional caches that make the feature possible.
