Great, thanks for doing that!

I understand that you think the improvement for the non-default
placement strategy makes sense to the "default" too. Though the
"default" is somewhat intended not to be affected by any "placement
strategy" so that the behaviors of existing pengine test cases and
users' deployments remain unchanged.

For "utilization" strategy, load-balancing is still done based on the
number of resources allocated to a node. That might be a choice.
