Answer
It prevents invalid data from reaching the service layer.
Early input rejection, using annotations like @Valid, stops invalid data at the controller level, ensuring that only valid data is processed by the service layer. This reduces errors and improves application performance by avoiding additional validation checks further down the line. For example, rejecting a null email at the controller level avoids unnecessary processing.
