Some of the changes would not seem that obvious if you only fly the A320 series, however these SOP changes are across all types, the CM2 power up flow makes more sense when on the A380 or A350 which has integrated OIS, CM1 would be getting the techoog and OIS setup.
The SOP has to be consistent enough to allow MFF, CCQ, and CTR where applicable. Longer term I would see the A320 moving towards having blade servers and avionics living as applications on these blasé servers like the A380/A350 instead of individual LRUs like the A320. I would see the future cockpit be more like the A350.
