I have a follow-up question: This day I realized that teeworlds broke on core-updates due to a freetype update (see https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30518). Now I thought: Is it possible to download the whole list of (directly) breaking packages from Hydra? If so, I could fold-packages through them and filter out those that also have freetype as a dependency and probably fix them with a one-liner. Is there any download/API functionality for Hydra?
