I think DRY should just die. It lacks any of the nuance of why copying code is a bad idea. I prefer thinking about a single source of truth and whether two pieces of code are semantically related rather than just happen to look similar. I also think identifying such similarities is hard without first seeing the repetition in a few instances and it is much better to add another copy than introduce the wrong abstraction; unless it’s really obvious then just wait for more repetitions first.
