Even though it'll be a long time (maybe never) before Solum is a core project, it'd be good to track the CLI work going on in the common client . The session at the design summit  definitely conveyed a broad agreement on this direction (ie common client is mostly inevitable), so being cognizant of the plugin pattern they have going is smart. We could potentially ship an isolated common client (ie based on that code) that used only a Solum plugin, so in the future we would have the option to switch to being integrated.
