Excesive errors in the logs related to shipping

nopCommerce version 3.0

I was seeing a lot of entries on my logs with this error:
Shipping (UPS (United Parcel Service)). UPS Error returned: UPS Rating Error, Error Code: 111210, Error Desc: The requested service is unavailable between the selected locations.

After troubleshooting I found that this errors was being generated on the shipping service (Nop.Service/Shipping/ShippingService.cs) in the method called GetShippingOptions.

The UPS shipping module was throwing that error when users were selecting "Spain" as the shipping country. I do have US and other countries enabled for shipping.

I had to comment out the line bellow doing the logging

foreach (string error in getShippingOptionResponse.Errors)
                    {
                        result.AddError(error);
                        //_logger.Warning(string.Format("Shipping ({0}). {1}", srcm.PluginDescriptor.FriendlyName, error));
                    }

Then I move that line at the end of the method like this:

if (result.Errors.Count > 0)
            {
                foreach (var item in result.Errors)
                {
                    _logger.Warning(string.Format("Error on GetShippingOptions ({0}).", item));
                }
              
            }

Because the Error collection gets clear between those two section if another shipping plug in is able to calculate the cost for Spain:

if (result.ShippingOptions.Count > 0 && result.Errors.Count > 0)
