Not an expert, but intuition suggests this probably isn’t true.
If an engine is going to fail spontaneously it’s almost certainly going to happen at high thrust, not while at idle or very low thrust values during taxi.
Your intuition is wrong.
Engines experience issues when changing speeds (especially start-up) not when at steady thrust output.
