Historically we've been very supportive of adding well designed domain specific packages. SymPy, in fact, was built originally with at least a partial desire for solving symbolic physics.
There are of course advantages and disadvantages in doing this. My personal opinion is that we limit GSoC projects to projects that improve existing SymPy packages, instead of adding new packages (core or not). I'd love to see a GSoC proposal that just listed 50 issues in the tracker that would be fixed. But these new package ideas do get people excited to work on the project which has value in itself. Its also easier for newcomers to wrap their head around.
