No Comments on Openstack: Are components related to a keystone::project auto garbage-collected upon project deletion?

Hello dear community, in the research of how to properly delete projects and their resources via the OpenStack API I was only able to find a hint in the official python sdk, the project_purge.py (docs). Here deletion is handled for "servers, images, volumes, snapshots, backups", but not for networks, subnetworks, floating_ip, ports, which are linked […]
