The only advantage I can think of is,
when someone DOES break into your car and DOES try to forcibly turn the key barrel with a driver of some kind, the key barrel drive to the lock pawl might break off, because of that pressure, and that may stop them from unlocking the steering mechanism.
You could try it an see if it successful but will be a mighty expensive repair just to prove an idea.
Leaving a vehicle with the steering lock pawl heavily loaded to hold the " torsional twist back" doesn't do anything as far as I can see. It is possible my eyesight is failing though.
Many people when turning off their engine DO NOT release the steering wheel so there is no torsional loading happening on the lock mechanism.
They switch off with when holding the wheel and this creates the difficulty to turn the key back on because of that pressure.
If you ever get to see the small amount of metal which actually unlocks the steering mechanism, so it can be driven, you won't continue to cause it anymore wear and stress and you will always free any shaft pawl lock pressure before you try and turn the key.
Think of it as a $$$$$$$$$$$ saving attitude.
The key should never experience any torsional turning resistance, it isn't designed to move the steering mechanism just to turn on the ignition. If you ever hear any crunch/bang as the key releases the lock pawl then it is being worked to the max. You break quickly when worked to the max also.
Why do some never give trouble and others after just a few years of use, stuff up/break/seize up ??? The awareness of the operator has a lot to do with vehicle component longevity.
If you hold the steering wheel against the lock pawl and forcibly turn the key you can break a brand new vehicle ignition key system before it is ever driven.
