Automated stall recovery?

Frequent SLF here, flying most of the time aboard A330/340's, better informed than average but that's it. I very seldom post. Feel free to ignore or delete if inappropriate.
I have two questions. It's not humanely possible to read each and every post on AF447 here (although I've already read a large part of them over the past years) so I've tried searching but failed to find answers.

1) when reliable airspeed information was recovered, did the flight control system switch back to normal mode with all the protections available or not? (I presume not). Is this by design?

2) would some kind of automated high altitude stall recovery be conceivable on such a plane? at least forcing a stick push action?
I find it so disturbing that the AB has so many protections to prevent incursions outside of the flight envelope and that none of this automation could no anything while the PF was holding the stick full aft for long minutes and the plane was stalled.

Sorry for the naive questions. This is *not* a attempt at restarting a new FBW pro-con war and I would be very frustrated if it did.
