Freso [1] filed a deletion request for python-backports.csv [2]: Backport to Python 2 of https://docs.python.org/3/library/csv.html Python 2 is EOL’d and this AUR package doesn’t provide a build for Python 2 anyway, but still existed since other AUR packages had it as a dependency. With the update of tubeup no more packages actually depend on this and it should be fine to remove from AUR.
