You have brought up a very important aspect of NSaaS that needs to be addressed. 

OpenStack completed the Firewall as a Service project and specified the set of APIs for Firewall services:

OpenStack has also defined the APIs for managing Security Groups: 

In addition, there is a "Security as a service by Cloud Security Alliance (": 
SaaS by CSA is at the initial stage of defining the scope of work.

OpenStack, as it is an open source community, its contributions are like IETF's individual submissions. While IETF's individual submissions require some levels of expert review before RFC can be published, OpenStack doesn't have this system. Basically, it is not required to have validation on correctness and completeness of the submissions. 

As the result, the attributes defined by OpenStack Firewall/Security as a Service are very primitive, e.g. only say "firewall rules" without explicit specification of what. In addition, 

One of the goals of NSaaS in IETF is to create a productive eco-system with OpenStack and other Open Source communities, with IETF defining specifications/protocols, Open Source communities contributing source code based on IETF initial specifications (potentially with enhancement), which in turn augment IETF specification, and then back to Open Source communities. 

The NSaaS can start with will the OpenStack defined interface, and move on to make them more complete and useable.

I think that what really needs to be addressed is that these previous efforts have been unsuccessful.  If the OpenStack project is seeing uptake, that's a big deal.
