MarsSeed [1] filed a deletion request for hydrogen-cme-git [2]: Abandoned, broken git package from 2019, for a not very active contributor fork repo (which atm is 489 commits behind upstream). [a] Not useful to keep. Arch/extra has the stable hydrogen package, and AUR has a proper hydrogen-git build.
