Problem is resolved in Bionic's latest version of cloud-init, released yesterday:
$ dpkg -l | grep cloud-init ii cloud-init 18.5-45-g3554ffe8-0ubuntu1~18.04.1 I've manually upgraded the package after bringing-up my EC2 Classic instance, so notice the AWS image doesn't have the latest cloud-init version yet.
