Lightning new URL format navigate to visualforce

The syntax /one/one.app#/alohaRedirect/apex/TestVisualforcePage is not dead yet and will continue to work. As stated here it's not recommended if there is an alternative, but sometimes there is still no alternative.

In one scenario on a current project, we have a CTI adapter that opens a screen pop in a new window, and we want the new window to pop open to a particular Visualforce page with the Lightning one.app wrapper around it, and pass parameters to the VF page. The CTI adapter does not have access to sforce.one or any Lightning events. In this situation we decided to use the alohaRedirect syntax because we simply could not find an alternative.
