Basically just used by speed runners and folks desperate to get some of the harder achievements. I don't like when devs patch things like this...it helps no one. The exploit wasn't harming the game or ruining any balance. And it's not remotely easily/accidentally discoverable. As someone who likes to complete achievements this is frustrating cause it means everyone who already got these harder achievements had an easier time ..and so the bar is different now depending on when you started playing. It just feels unnecessarily hostile towards the players.
