Hi Alvaro,
I am the editor of the I2NSF Applicability draft.
Let me answer your comments inline below.

       This draft describes how the I2NSF data models can be used for
cloud-based security services,
       such as firewall, web filter, deep packet inspection, and DDoS
attack mitigation, along with
       the SFC, SDN, and NFV at the aspect of the applicability of I2NSF to
the real world.
       On the other hand, RFC 8192 just gives the audience high-level
concepts for I2NSF use cases rather than
       the detailed use cases and applicability of I2NSF for real
applications.
       I believe that this I2NSF applicability draft will be useful for the
developers and operators
       to implement and operate the I2NSF system, so the publication of
this draft to an RFC will
       be required.

In order for this document to be an Applicability Statement, I believe that

      Thanks.

      Best Regards,
      Paul
