The Python jargon is that the "backports" shared by backports.tempfile
and backports.weakref is a "namespace package".

For Python 2, dh_python2 handles this: python-lazr.restfulclient and
python-lazr.uri are an example of cooperating packages that share a
namespace package.

For Python >= 3.3, the __init__.py is unnecessary due to
<https://www.python.org/dev/peps/pep-0420/>.

This is not necessary, and would probably (hopefully?) lead to rejection
from the NEW queue.
