Re: [quicwg/base-drafts] Short header reserved bits: make available for unilateral experimentation (#2022)

[Igor Lubashev <[e-mail]>]

@MikeBishop, if I understand it correctly, you are trying to solve a problem of how to pick two random random bits for greasing, if the sender is not using those bits for anything. I would argue that it is a relatively simple obstacle.

The real obstacle to a sender unilaterally using the two unused bits is _not_ technical.  The problem is WG's desire to prevent implementation of anything observable by the path for the fear that the sender will misuse the bits and accidentally reveal something that the receiver would object to.  I am a bit at awe at this position -- this is beyond the fear of a third-party middlebox vendor; this is a mistrust in the actual party to the connection.  Yet, the majority of the WG seems to strongly support just that position, so we may decide to declare it a consensus position.  In any case, I am glad this got discussed and seems to be getting settled.
