This was an alert to wind shear ahead which simply required a normal missed approach, rather than a wind shear encounter which requires memory items to be applied. The startle effect in an actual encounter is far greater and requires the aircraft to be accurately flown manually with the co pilot in the loop calling out the wind so they know when they can resume normal flight.
AUTO TCAS is available on newer Airbus aircraft, perhaps wind shear needs an automatic response from the aircraft as well. This isn't what I would expect to see from a crew in charge of any commercial jet, let alone an A350.
