[Python-Dev] Process to remove a Python feature

To be fair, if they hadn’t already been deprecated we would have had to deprecate the old behaviour for a couple of releases before changing it. It just so happened that we did the deprecation first without knowing what the fix would be :)

About deprecation, there is the funny story of bytes filenames on
Windows. I deprecated this feature in Windows 3.3 since it was broken.
I really wanted hard to remove support for bytes filenames on Windows.

One day, Steve Dower showed up with the PEP 529 "Change Windows
filesystem encoding to UTF-8" and he just *removed the deprecation
warning* from Python 3.6, since bytes filenames are now working as
intended :-)
