As a member of cmohuskies21's league, I fully support the addition of these stats. They seem to be excellent indicators of a pitcher's overall skill, and also neatly complement stats that are already offered on the hitting side of things. If you have OPS for hitters it makes little sense not to have OPS against for pitchers. If there can only be a limited number of categories it would make sense to do away with one of the less useful or infrequently occurring categories (perfect games?) and replace it with OPS against.
