I'm curious what led you to making this change in the first place.  Did
you observe a problem or was it more theoretical?

There is a cost to take on added complexity.  I just want to make sure
we're solving a real problem and not looking at a micro-optimization
compared to the cost of the operations generally being performed by
OpenStack services.
