Public bug reported:

limits API policy is allowed for everyone but policy is default to
admin_or_owner[1].

This is because API does not pass the project_id in policy target so that oslo policy can decide the ownership.

and if no target is passed then, policy.py add the default targets which is nothing but context.project_id (allow for everyone try to access)
- https://github.com/openstack/nova/blob/c16315165ce307c605cf4b608b2df3aa06f46982/nova/policy.py#L191

There is no owner things in limits and every projects can get its own
limits. We need to make default to RULE_ANY which means allowed to
everyone.
