Bug Description

The code for replication 1.0 was removed with the patch for Replication 2.1 (cheesecake):
https://review.openstack.org/#/c/275797/35

So the APIs for os-promote-replica and os-reenable-replica are gone, but were never deprecated (I dont' think).

We should likely have something in the release notes for this.

This happened in Mitaka after a lot of discussion with the only implementer of replication v1 support. It was decided since there were a limited number of users and it would make things more difficult and confusing to be able to implement replication v2.

Right or wrong, that's the history on it.

That's fine. I'm just wondering if we should have any documentation or releasenote for the fact that the apis are removed?
It came up during review of this:
https://review.openstack.org/364680

If we don't want to document, I'm OK with that. I just wanted to bring it up and see if there's something that should be done.

I've added a release note on that in Newton's release notes with the dead code removal patch [1]. Is it worth adding it to stable/mitaka?
