MarsSeed [1] filed a deletion request for buck-git [2]: Orphan, unneeded Python2 + Java VCS package from 2020. Upstream repo readme says: "Use Buck2 - This repo is dead. Please see https://github.com/facebook/buck2 for the build system that replaces it." [a] There's still a stable package for this on AUR, carrying the last release version.
