AP must be used for all departures and arrivals
Ummm, care to run that one by me in the light your QRH and MEL or will you be rewriting them as well???
What about always using the autothrottle until the day it fails and it's Cat 11?? No autothrottle ain't a stopper for most aircraft. Do you divert? Is that in your book?
How will you get into Schipol, CDG, Muc or the rest of the Lnav airports if your autopilot goes twang? Divert?
Sitting down it all sounds sensible and safe but the reality is your MEL, QRH and company manuals will expect you to dispatch/continue. And loads of you are subscribing to a culture where simple failures are effectively emergencies due to lack of practice. You go off duty shaking your head and get deeper into the 'it's not safe mindset' because it was bloody hard work.
Here it is in a nutshell. If a company document, any document allows/expects you to launch or continue flight without an autopilot, flight director or autothrottle it isn't an emergency, it's something you should regularly practice - not frighten the other guy coz you're in the sim next week.
