 * @assertion In a migrated library, override checking must check that an
 * override is consistent with all overridden methods from other migrated
 * libraries in the super-interface chain, since a legacy library is permitted
 * to override otherwise incompatible signatures for a method.
 *
 * @description Check that if opted-in class extends legacy class, migrated
 * method with non-required nullable parameter can override legacy method
 * with named parameter without default value.
