Appendix A.  Historical Parallel

   The following timeline is offered for context:

   1989:  2 Live Crew releases "As Nasty As They Wanna Be".  Federal
      authorities take notice.

   1990:  Skyywalker v. Navarro finds the album obscene.  2 Live Crew
      responds by recording "Banned in the U.S.A.", sampling Bruce
      Springsteen.  Members arrested performing their own music.

   1992:  Eleventh Circuit reverses the obscenity ruling.  "Banned in
      the U.S.A." is no longer banned.

   2018:  TLS 1.3 is published as [RFC8446].  Null cipher suites are
      eliminated entirely.  One zero-byte IKM remains.

   2026:  This document proposes filling that zero with the hash of the
      audio that survived its own institutional suppression.  The circle
      is complete.
