Sorry, I should have said: I think this is an interaction between DRF
and django-filter: django-filter is 0.11:

    python-django-filter/xenial 0.11.0-2 all

and requirements-prod.txt has 1.0-1.1

I was pointed towards the filters/DRF interaction by:
http://stackoverflow.com/a/41477856/463510

I'm still digging in to this but I wanted to flag it in case anyone had
any bright ideas.

We still need to fix this for the reasons in my original email. I also
can't find a system package for drf-nested-router, which will also be an
issue for deployment on sites that want to use system packages for
stability and security update reasons.

Daniel
