That's not the scenario that this mechanism seeks to avoid.  The idea is that a new connection is less likely to time out during the (non-idempotent) request than one that has been sitting idle for a while.  This is a hop-by-hop thing.  

Obviously, if the request was going to fail anyway (at any hop), there's no gain.

We seek to do away with such heuristics.  They are brittle and inefficient.
