There is a need for a central place where deprecations are
posted. You can't tell people to go hunt the standard lib
for uses of the warning module in order for them to catch
up with the current state of affairs.

One thing that we shouldn't forget is that Python users
do not necessarily upgrade to new Python releases every time
there's a new release.

Production users of Python will often skip a release
or two depending on their needs, time frames and audit
cycles. It is very important for them to know that module
or other technology will be deprecated two releases down
the road, so that they can accomodate for these changes
