EINull: Memory is not so accurate, and you ask why Boeing changed it. Go back a little further, B757/767 perhaps even B732 and I believe GS before LOC was possible. I can't remember B733. Therefore there had been change in philosophy not to allow it as standard on NG's. Could that have been an FAA/JAA thing? Or just 'why would you want to?' VMC you can follow GS guidance off LOC safely, without being captured. IMC not good idea.
