I can assure you they read these papers. If it is good, it will be part of a future version of the software.

100%, Its how we managed to justify flying out to siggaph each year.
The foundry have been trying to get this into Nuke for years. The problem is that normally you get flickering, as you'll have seen.

Are there no tools that automate the cleanup of green-screen artifacts?
Green screens are crap with hair, because its translucent the green/blue bleeds through which means that it has to be cleaned up by hand.
Then there are the situations where there isn't a green screen. Again manual cleanup is required. Each frame needs to be cut out by hand. 24 times a second.
The same with a difference matte. Cameras are noisy, so there is constant noise in the alpha channel. This makes the effect look wobbly and cheap.
What this method does is pull a key from a difference matte, and makes it look good.
