If it cannot, it responds asynchronously. The mechanism works rather effectively when dealing with long running processes. I respect that you might not consider such use to be "sane" but it has proved useful nevertheless.

Right, but what's the difference between:

  Prefer: wait=10
  Prefer: return-asynch, wait=10

? "return asynch" really says "give me a 202" which is nonsense; the client doesn't control the status code, the server does. 


P.S. I hate that "h" on "return-asynch"... :)
