This is generally considered insecure because it may reveal sensitive data [1]. Furthermore, it happens that the default Ceph perms cause fatal ERRORs with this setting: 1) when Glance wants to remove an image, it cannot list children because Cinder or Nova might have created a linked volume clone behind the scenes and it is put in another pool (volumes/vms) which Glance cannot normally access; 2) when Nova wants to create an image, it lacks permissions to write to the images pool. Thus, I propose that Kolla Ansible stops setting this by default and relies on the working defaults. The downside is that this disables optimisations in Cinder and Nova. On the other hand, these optimisations have nasty behaviour of being linked directly to the original image, preventing its removal.

Kolla Ansible
The Kolla Ansible is a deliverable project separated from Kolla project.
Kolla Ansible deploys OpenStack services and infrastructure components in Docker containers.
Kolla's mission statement is:
To provide production-ready containers and deployment tools for operating
OpenStack clouds.
Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.
Getting Started
Learn about Kolla Ansible by reading the documentation online Kolla Ansible.
