Or, in the Flex 4 model, you can but an empty rectangle in the 'space' that you need. It doesn't carry the weight of a whole component and is much more performant. I wouldn’t object if you wanted to have a graphical element which just was used for spacing. It's not ideal in my opinion but I get the reason. Having a whole component with all of that overhead and a lifecycle just to space something out though is really wasteful
