Unless you have tried git subtrees, I doubt you really mean this. How
is a 'make refresh' command as comparable as manually pulling in
changes from a project to your project?

Portability of kconfig to other platorm is a topic of its own. If that
sort of conversation can exist, I think it would have to be *secondary*
to deciding whether or not kconfig lives on its own to allow other
Linux projects to benefit from it.
