How do I add a System Right?

Due to the earlier messages on the list today about restricting access
to the Statistics tab, I’d like to add a “ShowStatistics” system right,
there doesn’t seem to be any clean callback/overlay way to do this,
which leaves me with making a copy of in local, which I’d
really like to avoid.

Am I missing something?
