Re Openstack support. I've raised an issue on the terraform-openstack provider to get their vendor dependencies straightened out (https://github.com/terraform-providers/terraform-provider-openstack/pull/359) they approve of the change but need to fix some breaking issues and ensure stability before merging it. Once that's in pulumi-openstack can depend directly on the official terraform provider.
Has there been any further thought about pulling in the OpenStack provider as an official repo? Even if it's just advertised as alpha quality it would help giving it a stable package name.
