MarsSeed [1] filed a deletion request for python-billiard3 [2]: Unneeded old release from 2021 of extra repo's python-billiard (v4).
Nothing requires it on AUR, and it conflicts with the latter package. Safe to delete. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python-billiard3/
