MarsSeed [1] filed a deletion request for rst-proto-stable-git [2]: Orphaned VCS package. The https://projects.cor-lab.org website's SSL certificate has expired. Shows only an empty loginwall when HTTPS is skipped. No identification of what this was. Not even available from web.archive.org. (cor-lab.org redirects to "Cor-Lab" at the Universität Bielefeld: Research Institute for Cognition and Robotics.) From the dependencies it seems it was using Python 2: it's missing python2-protobuf. Google discontinued Python 2 support last year, and it is a binding for the binary protobuf library, so the old Python 2 code is now incompatible an unworkable. The source came from the site's hosted git repository. It also doesn't work anymore. The HTTP server enforces HTTPS but git refuses to connect due to the invalid certificate. Using the unsecured legacy git:// protocol leads to the server not responding at all (timeout). I was not able to find alternative sources or websites for the project, so it seems it's unmaintained and has been discontinued. Safe to delete this package; only AUR/rsb-process-monitor-git depends on it from the same dead project (deletion request to be submitted separately).
