Hi Ed,
Most of the cheaper DRO's like the Meister, Sino etc have the option of summing or not at the push of a button. The carriage hand wheel is not much good for fine feeding so this is where the compound scale shines.
I always lock up the carriage and dial in the last bit with the compound for facing etc.
Saying that you don't need the compound one for setting tapers with the DRO as thats done with just the carriage and cross slide scales.
For people without a mill and using the lathe compound as a milling attachment, the compound scale would make milling easier as well.
