In many classes we have pointer to a client object. These references should be reported as weak pointers and the client's memory usage should be reported when the client is reached from its instrumented owner where we know exact type of the client. Otherwise we would need to add reportMemoryUsage to all client interfaces which place additional burden on the client implementers and blur the instrumentation boundaries.
