The reason for this is not necessarily that some version of Python might not have tzdata, but to indicate that this module is not basically an implementation detail of zoneinfo but rather a source of the time zone data available for anyone to use for whatever purposes they have. For example dateutil.tz will use it (including on Python 2.7), and I have long felt that pandas or some other library in the scientific Python space should implement their own time zone class that works better for vectors.

data for other time zone libraries. It is generally recommended that any time
zone libraries should attempt to use the system data before using the
``tzdata`` package, but some systems (notably Windows) do not deploy zoneinfo
