We actually should *not* make this a clang frontend only thing. It is confusing and not helpful. That said, we have code to integrate this into the new PM already as we were planning on proposing something along these lines too. We didn't manage to get to it during last years GSoC but the code could be used as a basis still.

+1 for RFC
strong preference for proper integration of this into the new PM.
