In the Speed+Mobility draft, we removed CREDENTIAL because:

   CREDENTIAL:  This is removed from HTTP Speed+Mobility because we
      believe it is not compatible with options such as TLS SNI.  For
      this proposal, a session MUST only target one origin as described
      in [RFC6454].

Concerns were also raised in "CREDENTIAL really needed?" (https://groups.google.com/forum/?fromgroups#!searchin/spdy-dev/credential/spdy-dev/WazzPBFbdpk/yayPrNTehYYJ). Based on the responses, it appears that CREDENTIAL was an experimental feature not used in SPDY/3, but intended to be replaced with a different design in the future; therefore, it could safely be deprecated or ignored.

I propose that CREDENTIAL be removed from the HTTP/2.0 draft. Related issue:
