Some quite modest systems have approved (certificated) wind-shear guidance and control which are designed to manage the conditions - some trading transit speed for climb performance based on excess energy.

With surprise and its effects on human performance, the technology will out perform the human, particularly in these rare and highly dynamic situations.

As much as it important to understand the situation, its vital that crews understand the design, operational assumptions and capabilities of their aircraft, systems, and technology; via education not rote training.
I was going to write something similar. The raw data could be all over the place and as a pilot what are you going to prioritise - speed, altitude, pitch, terrain clearance? They might all be in a bad way and following mathematically derived guidance would likely achieve a better overall result than just winging it. In a severe encounter it might be a matter of life and death. If you’re not going to follow the FD in TOGA/WS, how do you decide whether to pitch up or down and by how much? Whatever you do differently has a good chance of being suboptimal.
