I don't know if there's and discussion on it anywhere. And if there are no known issues, seems rather silly to remove it as it gives a pretty measurable boost to performance. For me it might not matter but for users who don't have as high end a machine as mine it could make a difference between playable and not.
You never know if something will be broken with speedhacks. I removed it from default, it can be set in the wiki for anyone interested to do it at their own risk. Metroid Prime isn't a very demanding game though even without the speedhack, chances are that those having trouble with it now will still have trouble in other dolphin games.
