Comment:
Replying to [comment:4 Tim Graham]:
> Is there a special reason for fixing this rather than adhering to the
[https://docs.djangoproject.com/en/dev/ref/models/querysets/#extra
documented policy for QuerySet.extra()]?
>
> This is an old API that we aim to deprecate at some point in the
future. Use it only if you cannot express your query using other queryset
methods. If you do need to use it, please file a ticket using the
QuerySet.extra keyword with your use case (please check the list of
existing tickets first) so that we can enhance the QuerySet API to allow
removing extra(). We are no longer improving or fixing bugs for this
method.
Agreed, let's not create a precedent.
