entshuld [1] filed a deletion request for ffc-git [2]: FFC has migrated to FFCx. The 2019 FFC is maintained in the `python- ffc' package which will still be needed as a dependency for other packages. Having a Git package of FFC does not make sense, and possibly a `ffcx' package will be needed in the future.
