1.  Introduction

   Privacy protection has been a growing concern in IETF.  [RFC7258]
   says that Pervasive Monitoring (PM) is a technical attack that should
   be mitigated where possible through the design of protocols.  This
   call of [RFC7258] is answered by emerging protocols, for example,
   QUIC [I-D.ietf-quic-transport].  QUIC is a new transport protocol
   designed to be secure.  Once a connection is set up, packets
   exchanged by QUIC are largely encrypted during transmission; only a
   minimal piece of information in the protocol header is exposed.  The
   encryption protects QUIC packets from being tampered by network
   middleboxes.

   Driven by concerns on privacy, the Internet has been accelerating the
   shift from using plaintext traffic towards using encrypted traffic
   [I-D.mm-wg-effect-encrypt].  Google started to offer end-to-end
   encryption for Gmail in 2010 and for searches in 2013.  YouTube
   traffic has been carried via HTTPS (or QUIC) since 2014.  In
   addition, the Snowden revelations [RFC7624] seem to cause an upward
   surge in encrypted traffic.

   However, it is also documented in [RFC7258] that making networks
