I completely agree, good point! Historically Chesterton's Fence is that you shouldn't remove something until you understand why it's there, but we should probably broaden the lesson to cover change of any kind. Something like, "Don't remove anything until you understand why it's there, and don't use something new until you understand under what conditions that new thing is better (vs. when it isn't)." I'm not against change, but I do hate the endless cargo cults.
