If the load balancer's job is to not direct traffic to 'unhealthy' instances, why does it not mark as down an Availability Zone with no registered instances vs. sending traffic there that then has to get bounced back to an Availability Zone with registered instances?

Or to look at it another way, if I setup registered instances in two Availability Zones and configure the load balancer to direct traffic to both and then one Availability Zone becomes dysfunctional, I'd expect a normal load balancer to mark the dysfunctional Zone/instances down and not try to direct traffic there at all.

Is this a missing bit of functionality that's a work in progress or is this the intended design?
