Some news to this topic:
The root/system users will stay not available in standard devices. It has to be ordered via the Service or STS. You will get a user assertion that can be imported to the ctrlX CORE and adds the system/root user.
For the virtual control there is a bug that the system user is gone in the version 1.8.x. This will be fixed in version 1.10 in RM 21.07. There is also an assertion ready as a workarround. Please contact the support for further help.
