What I describe is a simpler version of that. The key difference is that,
I only work out the dependency base on a distro config file. So there
is only one set of config value to generate a module instead of many
combo in the more general case. I think that will cover 80 percent of
what user want. If you have a known all config file, the reverse selection
is easy resolvable.

Care to CC them? I think most likely you need to touch the current
kconf for "make diet" any way.
