(speaking as WG co-chair)

Hi Leif & use-cases co-authors,

Thanks for your review.

Regarding :
"The security considerations section
refers the reader to the CDNI problem statement which is fine if
all the security considerations from RFC3570 (which is obsoleted
by this document) are carried over to the CDNI problem statement."

I would say that the fundamental security considerations brought up in RFC3570 are indeed covered by the Problem Statement. But arguably, there are one or two interesting specific declinations of these fundamental security considerations that are more explicitely spelt out in RFC3570 (eg "Delivery of Bad CONTENT"). My proposal would be that we catch all these "specific declinations" in our CDNI Framework document, since this is the target document for discussing specific declinations of system-level security issues (and each individual CDNI interface document will discuss its interface-specific considerations). 
Does that work?
If yes, I'll drop a note to the CDNI Framework authors to make sure they exhaustively catch any specific declinations of security issues that was brought up in RFC3570 and is not yet discussed in the CDNI Framework.

Cheers

Francois
