It does. But then, nobody was concerned about this when I indicated that I would be building many untrusted packages in koji and surely any automated system would issue its builds at low priority anyway.
These issues arise when we get to the point of running Review-O-Matic or RoM over the entire review queue, or over the entire repository to check for deviations from the guidelines. If we just look at the usecase of a reviewer using RoM to take care of the monotonous parts of a review, or a packager using it to sanity check his submission, most of these issues don't arise and it is still useful.
