huh? output can be whatever you tell it. Pre-Multiply is directly under output. Set output to none and premult to RGBA and you get your RGB input Premulted by whatever roto you have drawn in the node with only 2 nodes instead of 3. If you set paint node up the same way it does the same thing. You just don't get the overhead of the rest of the paint stuff being loaded into it.
