If you have an OS that keeps the system tz data up-to-date, I can't think of any reason why you wouldn't want to use it. If you don't have the data, why not include information in the documentation for how to download and install the database in a location that Python will search for, along with information on how to enable that?

Well, for one, that doesn't really fit in the "batteries included" approach. Having to download separate data files is an annoyance.

You could even provide a nice script that would download, install, and optionally enable that tz data's use.

This doesn't solve the update problem at all, since that tz data would still be outdated after a couple of months. In other words, it has no benefit for the user, but is more complicated to use.

Besides, that script would have to care about security issues. For example you'd use a HTTPS-enabled source, and then bundle the required CA certificates with Python. But wait, now Python has to ship some data that will possibly become outdated in a year or two :-)
