Export clients and related packages. The main rule is to not import internal packages from exported packages. The gateway client and related types are totally decoupled from the gateway service (not shared types between the client and the server). Instead the configstore and the runservice client currently share many types that are now exported (decoupling them will require that a lot of types must be duplicated and the need of functions to convert between them, this will be done in future when the APIs will be declared as stable).
