SmartObjectSubsystem not available on Client ?

Hello,

From SmartObjectSubsystem, I see some parts talking about replication like here :

	/**
	 * A map of registered smart object handles to their associated runtime data.
	 * Client side Smart Object Subsystem's will only have runtime data
	 * for Smart Object Components who enable replication, but server subsystems will have all smart object
	 * data.
	 */
	UPROPERTY(Transient)
	TMap<FSmartObjectHandle, FSmartObjectRuntime> RuntimeSmartObjects;

And then

bool USmartObjectSubsystem::ShouldCreateSubsystem(UObject* Outer) const
{
	if (Super::ShouldCreateSubsystem(Outer))
	{
		if (const UWorld* OuterWorld = Cast<UWorld>(Outer))
		{
			return OuterWorld->IsNetMode(NM_Client) == false;
		}
	}

	return false;
}

How can we retrieve SmartObjectRuntime on client side ? If we need asynchronous RPC call each time it will be complicated…
