Dear Michael and hackers,
This is a wrap-up of this thread. I'm planning to close the thread once.

OK, thanks for the clarification. Yes, there are no special path for
single-user mode for origins.
Now, senior members recently appeared here are not so motivated to restrict some
operations in single-user mode unless it cannot be done in principle. Based on
that, I decided to close the thread once until someone raised another point.
For the reference purpose, I attached a patch which prohibits slot manipulation
in single-user mode. Anyone can update and use the patch for any purposes.
Best regards,
