Deployment Pipelines Unsupported Items Error but why?

I've tried to use the new Deployment Pipelines feature today. I've assigned our existing Customer Services workspace to the pipeline and set it to Production deployment stage, however, I get the following error;

This workspace does not contain dataflows. I also get the following error when attempting to deploy to a previous stage.

Can't start the deployment

Most of the reports in this workspace use a shared dataset that resides in another workspace called Core Datasets, that workspace does have dataflows.

Three of the reports in the Customer Services workspace have their datasets in the Customer Services workspace and those datasets have dataflows as some of their datasources.

I understand that dataflows are an unsupported item, but I took that to mean that the dataflows themselves were unsupported, not datasets using dataflows.

Nimrod_Shalit can you explain the issue I'm facing here? As the documentation is written I seem to be using a supported configuration.
