What an odd feature to expose to the the user. User data partition is already encrypted. It would be enough with different boot option, chosen by the workshop with usb, fastboot or key combo, they could not access data anyway. Maybe its hard to explain to non techies why they need to power off their phone before handing it to the workshop. Otherwise this just sounds like PR stunt.
