Comment (by skorokithakis):
I think that thinking about this in terms of the value of the ID field is
misleading. The ID value being None is just an implementation detail, it
could very well be the future numeric ID (if Django could know this before
talking to the DB), in which case the query would become
`.exclude(related_field=<an ID that's not in the DB yet>)`, which matches
the intuitive reasoning behind that `exclude` call.
For that reason, i would strongly suggest option (a) that you mentioned
over the other two.
