Why not make a PR to add this to StructureMap.AutoMocking Repo?

I'm confused as to why there are multiple implementations of a StructureMap AutoMocker for NSubtitute. Shouldn't someone move this into https://github.com/structuremap/StructureMap.AutoMocking so it's side-by-side with RhinoMocks and Moq?
