Including deployments as merely steps in an overall "delivery plan" seems fundamental to calling Bamboo a continuous delivery tool. It has so many features that GoCD, CodePipeline, Jenkins Workflow don't have, but they all seem to embrace the principals of continuous delivery more so than Bamboo does because of this missing feature.
There are workarounds, but even a simple trigger for a deployment environment of a previous successful deployment would go a long way and I can't see how that is too difficult to add..
FWIW:
