I don't know what Django's backport policy actually is, but it would appear
both 1.8 (LTS) and 1.10 are still in extended support [1]. This performance
regression does seem like a viable candidate for v1.10.8 (based on how we do
thing in OpenStack land at least). I can chase this up if no one else fancies
doing it. I am also happy to add this to the documentation until that happens.

Correct. However, Django v1.11 support should be Patchwork v2.1, which I'd
expect to be releasing before years end (the 1.11 support patches are already
there, but I need to track down a potential performance regression first).


PS: Without a clear user, I think we should probably drop Django 1.6 and 1.7
support now. Will probably do that once 1.11 support is in there.
