Indeed it does, but it's also a workable pragmatic solution to a real 
problem. I could see putting a sunset date on the technique. You might 
also log a warning based on it so vulnerable admins could get a clue. 
This seems like a great way to move forward to me in spite of the 
unrelated RPC tying inelegance.
