True, I haven't looked at it closely. Not sure where it is in the priority list though.
However, I would recommend you _really_ look at _why_ you think you need cross-collection joins. Likely they will be expensive, and whether they're performant in your situation will be a question. If at all possible, Solr is much happier/more flexible if you can denormalize your data and live with the fact that your index will be bigger.
