Ben, In the 0.x baseline, the templates were stored in the templates directory that you're referring to. Starting in the 1.x baseline, the templates were migrated to become part of the flow.xml.gz. In order to support users upgrading from 0.x to 1.x, templates in the directory are automatically moved to the flow.xml.gz. If you're looking to automate template importing/removal, I would recommend using the REST API. If you open up your browser you should be able to see these requests in action. Additionally, you can find documentation for them here [1]. The import/upload endpoints are under Process Groups and the removal endpoints are under Templates.
