Which feature? Deprecation warnings tend to be in place for several years before removal. There's a formal policy for it: https://peps.python.org/pep-0387/ https://peps.python.org/pep-0387/ > Unless it is going through the deprecation process below, the behavior of an API must not change in an incompatible fashion between any two consecutive releases. Python’s yearly release process (PEP 602) means that the deprecation period must last at least two years. In practice, it's usually longer than two years, except on features that were considered provisional in the first place.
