Max age resetting after response

Is there a reason the max age is reset with each response? I need to be able to see if half of TTL has elapsed. The cookies expiration is being increased but the session still expires at the original max age.

   // proxy end() to commit the session
    var end = res.end;
    res.end = function(data, encoding){
      res.end = end;
      if (!req.session) return res.end(data, encoding);
      debug('saving');
      req.session.resetMaxAge();
      req.session.save(function(err){
        if (err) console.error(err.stack);
        debug('saved');
        res.end(data, encoding);
      });
    };

Fixing this would require a major version bump, sadly 😦 dougwilson added this to the 2.0.0 milestone on 5 Jan 2015

express 4 is out now, what’s the reason why the bug is not fixed yet?
