为什么微信静默授权不直接返回 unionId 呢？Why doesn't WeChat silent authorization return unionId directly?

In most business cases, the purpose of obtaining unionid by non silent authorization is to confirm whether it is the same wechat user; try not to harass the user according to the tone of wechat, and return the silent authorization to unionid, which is more in line with the tone of wechat.
