It isn't directly. the problem statement is different, and
for that I do recommend checking out the kconfig-sat effort.

It only indirectly relates in that we already know our kconfig
semantics need work, and I do think that the underlying problem
in this thread slowly strives towards addressing kconfig semantics
for modules, associating one main kconfig symbol with one module.

I have no evidence for this though. But since there are users who can
gain from it, I don't see any issues from embracing it.

Nope, this topic only ralates to yours in the semantics case.
