I get that, but why not make it an option? I don't understand what it does in the whole armature joining process but the fact that it forces you join all meshes is kind of retarded since the reason you would them separated is because you're still working on the fucking thing and it simply makes it easier that way.
So you either fuck around with the whole armature and might as well do the process manually then or you just move the mesh and get all your neatly-organized shit merged because unspecified reasons.
