On multiuser systems you can't (always) trust access from localhost.

In theory, accepting notifies should indeed not be a problem, but
because it accepts packets from the wire there is always a chance that
there is a bug in the handling of it.

Therefore we don't want to make that the default for everyone.

Does this make it more clear?

Regards,

Mark
