Much to my chagrin, our MySQL app relies on this. I know it's wrong, but it's what I have to work with right now. The table I'm using has a uniqueness constraint on a pair of fields, not just the ForeignKey. I override the pieces that expect uniqueness, but for the most part the ForeignKey machinery just works.
We were fine until validation got more strict.
