The whole airbus philosophy of manual flight is that if you don't touch anything nothing will happen/change.
As long as nothing fails. Engine failure is managed by yaw damper but has limited authority so remaining work pilot has to do. If something fails and aircraft goes in alternate law, pitch(rather 1g flight path) will be managed but roll pilot will have to look after. Airbus is going for more and more automation in A350. A320 is the first came in 88 so will not have everything later versions have.
