My take is the opposite. DRY can be overused, but it is much easier to “undry”, than it is to consolidate duplicate code which should have been dry from the beg

My take is the opposite. DRY can be overused, but it is much easier to “undry”, than it is to consolidate duplicate code which should have been dry from the beginning. Sections of duplicate code tend to drift apart over time, making it more difficult to consolidate down the road.
