For open repositories like this I certainly agree. And when I worked at a smaller company with no dedicated QA team we never closed bugs, either. But in game development with dedicated QA I feel such scrubs are necessary because when they're not done you end up wasting days just confirming that old bugs can no longer be reproduced and flagging them to be closed. Most bugs which linger are symptoms of other bugs which have been addressed. If they're still there they will almost certainly be found again by QA the moment you close it. In fact, old bugs often even have newer duplicates.
