+Spec Lite: Deprecate owner_is_tenant
+====================================
+
+:project: glance
+
+:problem: The ``owner_is_tenant`` option, which is True by default, allows an
+          operator to run Glance in a nonstandard configuration where the
+          image owner is the *user* who created the image.  In all other
+          OpenStack services, resources are owned by the *project* (as
+          they are in Glance when the default setting is used).
+
+          A survey of operators conducted in March 2017 indicated that
+          no operators who responded (14) are using this option.  As it
+          is little used, results in a nonstandard OpenStack experience,
+          and complicates the Glance code, the option should be deprecated
+          in Rocky.  Following the standard `OpenStack deprecation policy`_,
+          it should be removed early in the 'S' cycle.
+
+          .. _`OpenStack deprecation policy`: https://governance.openstack.org/tc/reference/tags/assert_follows-standard-deprecation.html
+
+:solution: Use the oslo.config facilities to mark the option as deprecated.
+           As it appears that this option is used only in its default setting
+           of True, no migration path is proposed.
