If you look at the traditional sub-frame (like used by CMC), it looks like they went with the least welds need (less labor). The main body 2x4" is very strong - but the piece to hold the rear - not so much. The cross member adds strength by triangulation. I always thought it would make a good rear hanger for a T4 or Subaru engine - BUT it really isn't very robustly supported. With all that steel and triangulation on VDUBs the cross brace probably isn't needed for support - but it does provide a place to anchor the heat shield over the exhaust system.
