This is already possible, you just need to get the scaling policy alarm URL into the instance where the application is running. I believe Zane was referring to: https://blueprints.launchpad.net/heat/+spec/update-hooks This is also related to the action aware software config spec: https://review.openstack.org/#/c/98742/ So in future, you might autoscale nested stacks containing action-aware software config resources, then you could define specific actions which happen e.g on scale-down (on action DELETE).
