Sorry for the vague comment, it's not the tracker the solution but EnsureTypeMeta therefore where we set the handler (just above, it eventually calls ReconcileKind) we need to call EnsureTypeMeta

	gvk := messagingv1.SchemeGroupVersion.WithKind("InMemoryChannel")

	// ...

				AddFunc:    controller.EnsureTypeMeta(impl.Enqueue, gvk)
				UpdateFunc: controller.PassNew(controller.EnsureTypeMeta(impl.Enqueue, gvk)),
				DeleteFunc: controller.EnsureTypeMeta(r.deleteFunc, gvk),

that ensures that whatever object is passed to callback has the Typemeta based on gvk

Okay thanks that makes sense!
