You could definitely use that, but a VFDeployer already creates a VF for you - how that is created should be impl detail; e.g. currently it is created via VFF, in the future it might be something else Hence you should simply pick up VF from DeploymentUnit's attachments and properly apply it in our Bootstrap deployer.
