There is a good question in the linked ask.openstack.org question:
"Let's assume you made this change so only admins could upload images. Would this affect non-admin users' ability to take snapshots?"
that's a really good question - its possible that because the service account for nova is actually creating the snapshot of a vm, this just works but that would need to be validated.
