I'd like to request an exception for https://review.opendev.org/c/openstack/releases/+/856128.
This patch proposes a new tooz release for the purpose of picking up [1], which fixes a bug [2] (it's not a feature, per se) that otherwise prevents tooz's etcd3gw driver from working with recent versions of etcd. The issue was initially observed back in 2020 [3].

Thank you for your consideration,
