GE logic editor design proposal

Hey, I came across this new proposal for the logic editor based on nodes (like when compositing). Heres a link:

I think it’s been posted before, but a huge leap foward from the bricks, do note that when the logic bricks were created Blender didn’t even have nodes (much less a node editor window)

A good part of it being able to reuse the hole logic graph and being able to implement various graphs to one particular object while setting their priority within the system. But it has to be created apart of the object. Why?
