I'd tend to answer that if it's an user problem, then I would prefer to 
see the orchestration done by a python-novaclient wrapping CLI module 
like we have for host-evacuate (for example) and deprecate the REST and 
novaclient APIs so it would still be possible for the users to get the 
orchestration done by the same CLI but the API no longer supporting that.
