Partial autopilot disconnect

CJ's quote: "Finally, the autothrottle did leave the power at the last setting.
Whether it would have been preferable for the autopilot to have reverted to a basic attitude hold is IMHO very much an open question, especially in turbulence."

At the moment of autopilot disconnect, main concern is to fly the a/c.
In Alternate Law, some attitude help would be welcomed, IMO.
Reverting to the last attitude could have given more time for the pilots figure things out.

If autothrottle left the power at the last setting, why not have also an attitude hold at the last setting?

IMO, anything that can give more time for the pilots, is very welcome.
UAS is an emergency situation, and in a very complex FBW system pilots need time to sort things out. Autopilot should give a "hand", basic attitude hold. This will not bring an a/c down as fast as an inadvertent stall.

Just a thought...
