Exactly, the main part in modern day Upset Prevention and Recovery Training (UPRT) is the prevention part, still we train recovery from undesired aircraft states because they do occur in real life and you need to know how to safely recover from those.
Loss of control is not always due to pilot deviation, it could be weather related, wake turbulence, mountain waves, icing, you name it. These things do occur and will continue to occur.
Its important to train these events as they can be disorientating and startling when encountered for the first time unexpectedly. And its a big benefit to do UPRT in a “full envelope” aircraft to really go inverted and try to resist the “panic pull” for example.
