With OSC 4.0.0 we could now use the --boot-from-volume option to create a volume-backed server from the provided image. However, that option leaves the created root volume around since delete_on_termination defaults to false in the API. So while we could use that option and convert from nova boot to openstack server create, it would mean we'd have to find and manually delete the created volume after the server is created, which is more work than it's worth to implement the TODO so just remove it.
