How do you serve cached content without knowing the URL of the resource? Are you differentiating between object confidentiality and metadata (URL/headers) confidentiality here? I think these questions apply to the other use cases you refer to, but am not completely sure.

Right. To be clear, CDNs *might* be interested in mechanisms that allowed them to guarantee integrity to their clients while still caching (for example), but that's separate from the need to introduce a new flavour of proxy to the ecosystem.
