Well, as a regular compositor, and into set extensions and matte painting, I must admit it's very appealing.
At this point, note that the guy used more than copycat to reach his goal ( https://leonardo.ai/ + https://stable-diffusion-art.com/controlnet/ + https://learn.foundry.com/nuke/content/ ... pycat.html ) but yes, very promising...
I'd love BMD surprise us by implementing this kind of tool not years and years after Nuke does. I was yet very pleasantly surprised when after I just tested out some python implementation I found on the web in 2019, BMD realesed their Magic Mask and Depth Map and surface tracker not too late afterwards.
This principle of training your own tools would indeed be cool to perform set extensions and matte painting.
I didn't take time to read this so far but I will
