A better formulation of DRY is SPOT (Single Point Of Truth). Definitions (code, data) that represent the same “truth”, i.e. when one changes all have to change to represent a consistent truth, should be reduced to a single definition…
Having said that, the cost of creating dependency chains is often underestimated. Overly dogmatic adherence to SPOT/SST can lead you to make the wrong tradeoff on coupling two unrelated areas of your codebase to unify some trivial truth. - DRY is an over-rated programming principle?
