I am not against the idea of having a single switch which knocks out protections But the idea of no auto trim in manual flight goes against the concept of AB FBW. Flight without auto trim for substantial amount of time will require some tactile feed back in the side stick. It is almost changing airbus to Boeing FBW. I do not think it is going happen nor it required. Coming back to 447 what would have helped and has helped in some other such events is sensible piloting and following proper procedures. But some how that is not important to you. You sarcastically used the phrase pilot proof aircraft but you are actually demanding better pilot proof systems because you support pilot's lack of skill. FBW feels the same at 35000ft. or 10000ft. but a 747 or 707 doesn't. AF447 crew the way they handled A330 could flying manually very well stall a 747 at FL350 even with valid speed. Continuity of stall warning sure nothing against it, they ignored it 50 times may be 51st time they would have heard it but the problem was not the stall warning but not knowing what to do with it. Auto trim just trims what you asked. Should a pilot ask for upward trim in stalled condition?
