MarsSeed [1] filed a deletion request for reduce-svn [2]: Abandoned, broken VCS package from 2019.
I don't think it is useful to keep, seeing no maintainer interest for years. There are newer and seemingly working stable packages for this codebase on AUR. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/reduce-svn/
