 The ghc-proposals process has proved robust, in my opinion. We should
 explicitly state that such a process exists and point users to it from the
 manual.

 This came up as I was documenting the solution to #15743 in the manual.
 The end result there is very much a free design decision, and I wanted to
 invite readers to propose changes if they disagree with the design. But
 there's no good way to do so, currently.
