Google Play Billing Library 2.0：是否必须确认旧的非消耗品购买？
Google Play Billing Library 2.0: must old non-consumable purchases be acknowledged?
我目前正在将现有应用从 Play Billing Library v1.x 切换到 v2.0。
对于非消耗品的应用内购买（例如解锁高级功能的一次性购买），这如何适用于 Google 引入确认之前以及应用使用 Play Billing Library 之前进行的购买v2.0?
他们能被认可吗？他们必须得到承认吗？如果必须承认，我想没有“3天”的限制吧？
根据 pencoba 在 GitHub 上的说法，他做了这个测试：
I've tried an experiment. First I bought an IAP using AIDL (without
acknowledgement) then using Play Billing 2.0.0 I checked if it's
acknowledged, the result is it is acknowledged.
然后由 Google 的人确认：
Purchases using AIDL directly or a billing library < 2.0.0 will not
need to be acknowledged by your application. When you query these
purchases via our server APIs or through billing library 2.0.0 they
will be marked as acknowledged. I will work on clarifying this in our
documentation.
