Translators aren't invisible to other users, they also run and start
as the owner/group of a file/directory node--to be exact, the
owner/group of the underlying node. So since they are running with a
different permission set they can't compromise your security.

I'm forwarding this mail to bug-hurd, so that Hurd designers can
clarify these issues.
