I think before we expose the active flag for these entities we should hash-out why the user would need to see it.  My original intent for the field was to use as a pseudo-delete mechanism -- something that wouldn't be exposed to the client/caller but would be set to false when a record is deleted (versus truly removing the record).  We're not actually taking advantage of this field at the moment in that capacity, however, so its future is up for further discussion -- including whether we keep it or not.
