I suspect they might be worried it could reproduce copyrighted code in certain circumstances, so their solution was to condition the model to never produce large continuous chunks of code. It was a very noticeable change across the board.

I thought it would be for performance, since it doesn't output all of the code then each reply is shorter/quicker. Although you can still ask it to generate more of the code but that introduces some latency so there's less overall load.
