I know that quite a few procedures have been re-worked that were originally designed with the 737-400, and the 7/8/900 series just cant make the turns with stab flight.
Don't throw the 700 in there, it is usually a lot slower during approach than the classic (300/400/500). Vrefs are quite often around 120kts whereas the 800 has them more around 140. I have done approaches with a Vref as low as 112 kts in the 700 which can be quite embarassing compared to all the other traffic around.
