On a non toroidal transformer this would likely increase the leakage inductance which is akin to putting another inductor in series with the transformer but likely not a very big one. For power supplies that could quiet them down but could add acoustic noise. Toroids unlikely to do much. Output transformers it could hurt your high end. If the product has a steel case less impact overall.
