After doing the same against my tree, I have discovered that the
following rules are in the same class (unreferenced productions),
but don't match the pattern '*-no-SA-handling':

  pre-zei-bu-no-SA
  zei-clause-no-SA
  bu-clause-no-SA
  BU-clause-no-SA
  BU-pre-no-SA
  LEhU-clause-no-SA
  LEhU-pre-no-SA
  ZEI-clause-no-SA
  ZEI-pre-no-SA

I believe they can be removed too.
