#8: Direct mode for key agreement needs security analysis

 JWE specifies a "direct encryption" method, in which the output of key
 agreement is used for content encryption instead of key wrapping.  This
 scheme is not used in other IETF security protocols that use key
 agreement, e.g., CMS or IPsec.  CMS uses the agreed key for wrapping.
 IPsec uses it to key the IKE SA, which covers further key agreement.  The
 security considerations needs to justify why this scheme is secure, and
 any relevant constraints (e.g., lifetime of DH keys).
