The management binary is embedded by downstream builds that override server construction via SetNewServer, but the cobra command tree itself was closed: rootCmd is unexported and fully assembled in init, with no way to attach additional subcommands. Customize hands the built root command to a caller-supplied function before Execute, so an embedding binary can add its own commands next to — or under — the built-in ones, such as extra administrative helpers beneath the existing admin group.
