I was about to say the same thing as MZ5 said - in modern motorcycles, rear disc brakes are powerful enough to lock up the rear tire, without the assistance of engine brake. That might not hold true a few decades back where rear drum brakes were still the norm. Having additional braking power from the engine might help you in panic braking situations. Now days, the rear braking power limit isn't the brake itself, the "breaking point" is the rear tire traction.
