This technique is useful if you want to use Q objects in conjunction with
the get or create method, and it's documented in a few places around the
web.
I brought this up in the forums yesterday and somebody suggested that it
be documented:

/django-developers/e3sJ6OiHEd0/Yrg-Z9uRAgAJ
I gave this a try, but I don't understand the documentation system and I
sadly don't have time to figure it out. Seems though like a change could
go here:
https://github.com/django/django/blob/master/docs/ref/models/querysets.txt#L1886
I think something along the lines of:
> get_or_create() can be used with Q objects by chaining them together
like so:
> An example
> When this is done, the logic performs as above, but matches are made
according to the query in the Q object.
I imagine this also works for update_or_create, but I'm not sure how to
document that too. Maybe just a quick mention:
> update_or_create() can be used with Q objects using the same technique
as documented above for get_or_create()
