My personal opinion is that if the control system cannot realize the full potential of the rest of the airframe, then it is a fail.
Thats a lot of failure modes to contend with.
On the one hand, the pitch up might have been a sincere attempt to protect the airframe. The control system can't query the airframe directly for its structural loads. Maybe it should in some clever way. As long as it depends on the go between - probes pitot - to deduce this info, its in a no win situation. If the pitots go kaput, all bets are off. OTOH if it wasn't the pitots icing up, some other failure would have led the control system astray. The sad fact is if the a/c inadvertently ends up in a cb all bets are off. Given that, there is still scope for improvement in Wx systems and training. IMHO.
