BouleJaune [1] filed a deletion request for rnix-lsp-git [2]: The project has been abandoned for years because the owner is sadly dead. The package doesn't really work and may cause security issue. The project has been archived on github in January. Alternative project are nil and nixd, which are maintained and growing.
