Why not promote the pilots, like in other well paid jobs
one should fly again immediately and of course as much as possible after whatever little mistake. Lets fly to the wrong rig again, just for training to see where it went wrong.
The big danger is to develop anxieties with this sort of ancient 'stand in the corner' guilt-building culture. Anxiety can be a serious blocker, especially for situational awareness.
The bold and thick chaps perhaps won't bother, but the sensitive and - usually - more talented pilots might receive the personal damage.
A bit contra productive, if not dangerous at at the end.
