Comment (by akaariai):
The problem with using annotate() is that is is used to annotate a single
value to the model, and in addition annotate works only for the main model
of the query, that is you can't annotate on some already select_related()
model. While this can be a bit limiting in some cases (say, two "latest
related" annotations in a row), it isn't that big of a problem.
Another solution is a new method, for example annotate_related().
The good thing about this is that there is still plenty of time to discuss
the API before the ORM can actually support "latest related" queries :)
