The factory service manual didn't mention it in the removal instructions, but the tool specified in that manual will prevent any motion, so maybe it wasn't thought necessary.
To take the slop out of the driveline you could push the car against engine compression until it is tight, then set the brake.
While I agree it can be a risk to rotate the engine backwards, I do not think that a partial movement will hurt anything. Of course, it isn't my engine ......
