This is nice, but does it scale? I don't think so. So my ask would be to
see if you can integrate the pico SAT patches to our shared kconfig tree
tree first under a new branch which branches out of the origin/yamlconfig
branch. Then merge that to kdevops and evaluate what a true SAT solver
can do. This let's us essentially lead the way forward for Linux.

The experiences we learn can be brought back to Linux.
