 One of the goals of the reference implementation is to maintain the number of dependencies as lower as possible. With that spirit, a modular approach has been followed, letting the users decide, depending on their workflows nature, which dependencies should be include. 
 
-In practical terms, this means a separation between the core part and additional dependencies that should be explicitly included if your workflow is interacting with an external service that communicated using a particular technology supported by the specification (at this moment, just HTTP). The intention of this is to avoid adding dependencies that you do not really need (for example, when gRPC call will be implemented, if we were adding the gRPC stack to the core dependencies, you wont be able to get rid of it even if none of your workflows use it)
