    Not including this means that SoftwareDeployments do not have a
    configured region (it's set to 'null'), and can therefore not
    communicate back to the heat API. In particular, this breaks Magnum with

Setting the region_name_for_services explicitly is a good workaround.

The cause was a regression in Heat: https://storyboard.openstack.org/#!/story/2005797
