The current solution proposed in the PEP is to have platforms
with /usr/share/zoneinfo use that as long as they want. For other platforms
Python would ship with a built-in copy (roughly speaking) of the database.
There would then be separate tzdata-update package on pypi that can be `pip
install`ed to update the timezone database whenever the user feels the need
to do so (because /usr/share/zoneinfo is no longer receiving updates or
because it doesn't exist)

What are the unsatisfied requirements of this design?
