Honestly, I don't see the point of removing PendingDeprecationWarning
anytime soon. Practicality beats purity. Python is no longer about the
purity of the language (we tried in Python 3.0, not sure that I want
to want to do that again ;-)), but making it convenient to use for
most people.

Removing PendingDeprecationWarning doesn't bring any value to anyone.
"PendingDeprecationWarning = DeprecationWarning" costs nothing in term
of maintenance.

If you care, I would suggest to invest time in static analyzers like
pycodestyle, pylint, pyflakes, etc. Emit a warning with a low
priority, and let users make their own choices.

And it's perfectly fine, no?
