I was thinking this very same thing as I read through this thread. I too would like to avoid the use of comp_masks if at all possible. The query call seems to be a verb where the structure size is all you really need to know the set of values returned. As Jason says, other calls may require the comp_mask where 0 is not sufficient to indicate "missing".
