Maybe in a racing situation where the brakes get red hot, or could fade ; where the engine is made to handle the stresses of downshifting.

Regular driving and wheeling shouldn't overheat our brakes. Save the engine unless your driving on a grade.

The brakes are designed to be safe under normal conditions.
