Hmm…. What would happen if Callback gets a default method which reports Scope::HEAP as a constant scope?  Then all lambdas spun by Java will have the correct classification as resources:  Nothing to free that isn’t covered by the GC. Binder created Callbacks would get both the resource and an override to the default scope reporter.
