On the other hand, by disabling a feature you may gain an increase in performance due to memory and processor utilization no longer being allocated towards the particular feature. Therefore disabling a feature should not be used as a method of freeing up hard drive space. It is important to note that in Windows Vista, when you remove or disable a feature, you are not actually removing files from your hard drive, but rather just deactivating them.
That DISM folder can even be copied and redistributed to machines if need be (speaking on functionality, I don't know if redistributing is actually allowed by Microsoft).
