I share the Gen-ART reviewer's concerns about the trust model that underlies SRv6. But it seems the source of those concerns is that actual spec (draft-ietf-6man-segment-routing-header), not this use case document.
Minor question regarding SPRING in Core networks (section 2.5): Why is SR here bettter than MPLS (which I guess is used today for this use case)? In general it would probably have been nice to also talk a bit about how this is better/different than existing technologies.
