It looks like a patch was merged into master for python-openstackclient.

https://github.com/openstack/python-openstackclient/commit/6868499ad9443960a158143c923da00ea86b7072

And we have been carrying this as a custom patch in stx-upstream

https://github.com/openstack/stx-upstream/commit/aceb7fecbaf103f4ed0b269e916f238881b5340f

I will remove the custom patch.  I will create a Launchpad so I have a value to submit against.
