I don't think it requires a userdebug build, since it's part of the functionality required by the CTS and the CTS only fully passes with a user build.

and

As far as I know, it exists so that the CTS can test the backup service implementation, so every Android device is required to have a working implementation of it that's certified to work as part of their CTS certification.
