Take a look at ticket #6095 to know the motivation and rationale behind the addition of the through option and some of the advantages when compared with using you own model with FKs to the two related models. Also and the documentation you pointed to modeltests/m2m_through tests show the usage of the new API that allows you to do the same things you were able to do but in a clearer way.
