Why redis.Exists() accept only one key in go-zero?

[striveQiao]

func (s *Redis) ExistsCtx(ctx context.Context, key string) (val bool, err error) {
err = s.brk.DoWithAcceptable(func() error {
conn, err := getRedis(s)
if err != nil {
return err
}

	v, err := conn.Exists(ctx, key).Result() // 这里go-redis是可以传入批量key的
	if err != nil {
		return err
	}

	val = v == 1
	return nil
}, acceptable)

return

}
这里可以加入多个传入吗，为什么只能传入单个啊
