> I notice that several utilities like ConsumerGroupCommand are implemented (hard-wired really) to be command-line utilities.  It'd be really handy for testing if these were broken out as Scala traits (that don't call println) with the concrete classes or objects being the command-line utility.
> As a trait I could create a thin wrapper class passing the same array of arguments, and instead of producing screen output the trait could produce result classes.  
> The command-line utilities (your concrete classes implementing the traits) could format screen output from the result classes.
> Why do this?  It'd be a really nice way for test code to query things like offsets and such after a test run.
