I did have it one time going into Biggin Hill when there was a twin (I was in a twin as well) doing massive circuits. After 2 requests from ATC to keep it inside the ATZ, he was asked to orbit at the end of his downwind leg and report ready to rejoin.
That's the way!
Problem with someone flying too far downwind in a busy circuit is that the pattern gets longer and longer until it becomes ridiculous. It can become unsafe because pilots on the downwind leg don't realise some numpty is coming in from miles out like a stealth bomber and will turn onto finals ahead of him.
