I don't understand why you think there would be an increase at files for deletion - the images will either be speedily deleted after 7 days, or have fair use rationales added, in which case they're no more likely to end up at FfD than any other fair-use upload. The speedy deletion after 7 days could be entirely automated, imposing no burden on anyone. As for outsourcing maintenance tasks to another project, it's not Commons' responsibility to re-upload images to local projects that are usable under fair use, and as important as it is, the burden of doing so would be enormous - we don't understand every project's local procedures or criteria, we don't speak their languages. I am just trying to shift the burden to the people actually capable of handling the task.
