I'm thinking about removing PendingDeprecationWarning. (previous discussion: https://discuss.python.org/t/pendingdeprecationwarning-is-really-useful/1038)
It was added "not be printed by default" version of DeprecationWarning. But DeprecationWarning is not printed by default now.
We use PendingDeprecationWarning for N-2 release, and change it to DeprecationWarning for N-1 release. But this workflow seems not worth enough for now.
I want to stop using PendingDeprecationWarning for new deprecation.
More aggressively, I want to remove PendingDeprecationWarning class, and `PendingDeprecationWarning = DeprecationWarning` for backward compatibility.
How do you think? May I do it in Python 3.8?
