For all I know, there may be some security reason why we really don't
want the automatic helpers, even if they can be convenient.

Also, you can just enable them with a kernel command line or a sysctl,
so it's not like you can't get the old behavior back.

Do networking people have any comments? Was there a reason to actually
switch the default? Because the commit messages aren't all that
helpful.
