Boolean Node
A node that has inputs similar to the 'if' node, but has 2 outputs: 'true' and 'false'.
I'd like to be able to simply branch the node logic, so that I can skip expensive calculation based on distance to the object being shaded. I'm not sure if there is another way to do this, but either way, a boolean node would be incredibly useful.

Generally it's cheaper to not branch, and instead render both and multiply the one with 0 and the other with 1, depending on your use case. It's also a question where you want to get the bool value from. What is true? Whether or not a value is beyond a certain threshold? For that, you can use the Step node. You might also want to look into the Toggle and Switch nodes
