Suggest New Section Before Conclusion Title: Current Industry progress and Major challenges on Telco CNCF Journey"

Do we think it is reasonable to include one sub chapter summarize industry current CNF journey .

E.g
1. Liaison with ETSI NFV Rel4 specs to define a Telco style definition of CNF and ETSI architecture
2. CNTT

Major Challenges:
1. Wrtie a bit about Networking specially out of box integration with 3rd party SDN ? will native NW fulfill Telco Service needs
2. Performance bench marking , how Telco can apply this practice to benchmark VNF in Gold , Silver ,Bronze to asses whether Application is infact CNF

Just an Idea , frankly speaking If I am the one in operator this the section I will love to hear the latest progress and issues that we collaborate to solve .

Review the document section immediately before the Conclusion title and the proposed references to ETSI NFV Rel-4 and CNTT. Define and agree on a new industry-progress and major-challenges section covering CNF architecture, networking integration, and performance benchmarking; completion requires approval of its scope and content.
