Or it just downloads the rpms headers, or whatever? Can we have a persistent compose root directory as base, then download the latest builds (if newer), do the pruning "based on something", create the repo and save the state as the base for the next run? Or will that eat way too much disk space? On the other hand we could save bandwith because we would not download all the rpms which were not updated from the previous run... what's more valuable for our infrastructure, disk space or network bandwith usage?
