This is needed by devstack-gate and *not* devstack. We have been trying now for almost two years to get people to stop using devstack-gate in favor of the zuul v3 jobs. Please don't conflate this with devstack itself, it is not related and not relevant to this discussion.

In order to make other jobs run correctly we are asking you to stop using devstack-gate and use zuulv3 native jobs instead.

Again this has nothing to do with devstack.
