Boeing describes the Automatic Windshear Recovery as a Maneuver in the FCOM. It is quite clear on the procedures or actions to be taken. I am quite confident that if they didn't think it was a procedure to be followed, it would not be provided.

Boeing is also quite clear in the FCOM about your concerns by stating,
"WARNING: *** Severe windshear may exceed the performance
capability of the AFDS. The pilot flying must be
prepared to disengage the autopilot and disconnect the
autothrottle and fly manually"
In other words, it is quite possible to have a windshear warning at a relatively higher altitude and stay on automatics. More severe stuff requires manual flying. All bases covered.
As a final add on here for anyone reading this thread.....
Second TO/GA push on the ground does nothing to increase thrust, therefore manual thrust lever movement is required. As soon a s airborne, the pilot can "terminate the HOLD mode and cancel any derate thrust limits by a second press of the TO/GA switch after liftoff."
