| For example, it might be necessary to store a file on a server without exposing its contents 
| to that server. Furthermore, that same file could be replicated to other servers (to make it 
| more resistant to server or network failure), downloaded by clients (to make it available 
| offline), etc. without exposing its contents.

does not mention it, but I think that there was hidden 
(for this draft) motivation where reponse headers was 
served from originin server via https (that include 
Crypto-Key) but actual payload is served from another 
server. That content-encryption provides encryption
for that payload. Another Content-Encoding (Out-Of-Band)
moves payload to other server.


was mentioned.
