There are known gaps in scaling back / scaling down OpenStack Charms.
The relation-departed Juju primitive is essentially NotImplemented across all of OpenStack Charms. That needs to be addressed on the higher level, as a concerted effort across the lot of charms.
We are tracking this type of issue with LP tag: "scaleback" in order to get a hit list of items to start with, and so that we can identify any common themes or areas where we should focus first.
