Comment (by Chris Connelly):
I was actually in the process of writing a similar ticket when this one
popped up! As with what Debanshu Kundu stated above, my goal was to add a
join to a subquery. My solution was a lot lower fidelity - I used
`QuerySet.extra` to inject a placeholder table (e.g. `{{JOIN}}`) which I
then substituted with the generated subquery before execution.
This does seem like this could be done if
https://github.com/django/django/pull/8238 was merged, which is an
offshoot of #27332.
