True, this seems to be the easiest way. I've already used it
successfully.

OK. I will consider this. Probably, after the community call... (Or
before?)

Well, scripting... If you have issues like "feature X" does not work

such dependency, I am afraid you always end up with a system of the same
or equivalent complexity as the kconfig already has :). We'll see...
