Nonsense. If the application has cap_sys_admin then it is less contained and
more trusted anyway. If I went to the trouble to run an application in a
private user namespace (where it can have cap_sys_admin, but not targeted
at my tty) then it should be more contained. That's the point of targeted
capabilities.
