Re: [Tsv-art] Tsvart last call review of draft-ietf-rtgwg-net2cloud-problem-statement-32

[Joel Halpern <[e-mail]>]

My reading as shepherd of the inclusion of the mitigation references was 
that it constituted a fair effort to recognize that the community hadd 
not and was not ignoring these issues, and that any effort to better 
address the issues should be aware of the existing mitigation efforts.  
As an informational document it does not prescribe any of the 
mitigations as that would be inappropriate for the document.

I am sure the authors have further clarifications,
