As long as you don't set it to brake mode this should not be a problem but acceleration and pushing make up almost all motion in an FRC match because by definition to change direction you must accelerate.

In most (if not all) swerve drives that use bevel gears when the pod rotates instead of backdriving the cim the wheel turns slightly.
