With respect to you as list moderator, I disagree.

An already conditionally accepted library, Fiber, is fundamentally 
affected by what WG21 are up to here. An existing Boost library, 
ASIO, is fundamentally affected, hence its maintainer leading out the 
opposition to present developments. The Thread v5 rewrite is 
fundamentally affected, and shortly so will be AFIO which fair 
enough, is not a Boost library.

Most WG21 papers aren't as important to Boost libraries, and hence I 
would ordinarily agree such discussion is off topic. The feedback 
already received here about resumable functions I have already found 
valuable - I hope so have many other library developers here.
