to me they are 50/50 there useful when it comes to what might be in the game like with GTA, but when it comes to making sure people are of age to play the game there not always useful as kids can find ways around that age restriction by either getting there parents to buy the game for them or playing the game on there older siblings account so really it's only usefullness is what will be in the game like violence,blood,extreme language etc.
