Daniel, you can already separate and combine vectors in the composite. Use Convertor->Separate RGB and Convertor->Combine RGB
If we go for a change we could do the other way around. Instead of having separate/combine RGB to have sep./comb. Vector, and use it for colors or regular vectors. This is pretty much how GLSL syntax works (rgb can even be interchangeable by xyz in a shader). But this may be more confusing for the user. In the end they are all floats, and I don't think there is any clamping going on there.
