AGameNetworkManager not really doing anything?

I saw this question about raising UE’s network bandwidth. The accepted answer suggests modifying the following config variables on GameNetworkManager:

TotalNetBandwidth=32000
MaxDynamicBandwidth=7000
MinDynamicBandwidth=4000

I’m trying to follow the engine source code to see how the config values mentioned in the accepted answer have any effect.

I am looking inside AGameNetworkManager::UpdateNetSpeeds, which propagates the calculated net speed to the player controllers, but there is no code in the engine that ever calls this method. There is a timer that should run once per second to run this method, but the only thing that activates the timer is this method itself.

void AGameNetworkManager::UpdateNetSpeeds(bool bIsLanMatch)
{
	// Don't adjust net speeds for LAN matches or dedicated servers
	ENetMode NetMode = GetNetMode();
	if ( (NetMode == NM_DedicatedServer) || (NetMode == NM_Standalone) || bIsLanMatch )
	{
		return;
	}

	if ( GetWorld()->TimeSeconds - LastNetSpeedUpdateTime < 1.0f )
	{
		GetWorldTimerManager().SetTimer(TimerHandle_UpdateNetSpeedsTimer, this, &AGameNetworkManager::UpdateNetSpeedsTimer, 1.0f);
		return;
	}

	LastNetSpeedUpdateTime = GetWorld()->TimeSeconds;

	int32 NewNetSpeed = CalculatedNetSpeed();
	UE_LOG(LogNet, Log, TEXT("New Dynamic NetSpeed %i vs old %i"), NewNetSpeed, AdjustedNetSpeed);

	if ( AdjustedNetSpeed != NewNetSpeed )
	{
		AdjustedNetSpeed = NewNetSpeed;
		for( FConstPlayerControllerIterator Iterator = GetWorld()->GetPlayerControllerIterator(); Iterator; ++Iterator )
		{
			(*Iterator)->SetNetSpeed(AdjustedNetSpeed);
		}
	}
}

What am I missing? As far as I can tell these variables are meaningless.

Edit: No one is proving me crazy, so moved to bug reports.
