Comment 2 Link Dupont 2023-01-24 18:14:59 UTC

yaml is imported indirectly by urfave/cli. YAML files are not used as part of any configuration file format within yggdrasil, nor are YAML files supported indirectly by any sort of file reading or opening within the application. This bug does not affect yggdrasil.
