Oh, I forgot: The test for the topologyId is probably better written like this:

  template<class G>
  struct SomeClass<G, typename std::enable_if<
     G::dimension == 2 &&
     Dune::GenericGeometry::IsCube<
       Dune::GenericGeometry::Topology<
         Dune::Capabilities::hasSingleGeometryType<G>::topologyId,
         G::dimension
         >
       >::value
     >::type>
  { /* specialization for dim==1 */ };
