I may argue that anything within the Linux tree which point
_by_default_ to something outside the tree itself is broken. Say I try
to build a Linux kernel on a system with has its own non-kconfig
`/etc/kernel-config', I guess this would make the configuration fail.

Why ? Thing should be kept simple. kconfig's job is not to know about
the trillion file format which exist in the world, even more if the
implementation is made by building a command[0], executing it in a
separate process and reading the output. This is the shell's job. What
may be useful in the contrary would be to eventually teach kconfig to
read from <stdin>.
