MarsSeed [1] filed a deletion request for python-plac-git [2]: Abandoned orphan VCS package from 2017.
As there is no visible interest in this, I recommend deletion. AUR has a maintained stable package for the latest release version. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python-plac-git/
