Pensador- You answered your own question. You were not forced to disconnect th A/P you used the appropriate level of automation as prescribed by Airbus. That is, disconnect the A/P when it is not coping with the conditions and it is putting you in a situation that you don't want to be in. Under the conditions you describe, manually control the aircraft until you are accelerating and you are comfortable with your margin over Vls. Then continue to enjoy the art of flying or let the A/P do it.
