Isn't the merge backend faster? I thought that was the point of it.

I actually have this about 95% done, waiting for the patches to be polished. So I don't think it makes a good GSoC project (it would be stupid to start from scratch, and polishing my patches is a lame project).

I think this could be a good GSoC-sized topic. I'm going to adjust the title to be "better support for triangular workflows". I think they may want to examine other issues in the area, rather than drilling down on @{publish} in particular (but ultimately, it is up to the student to propose what they want to do).
