I'm still not happy with how this is likely to break users and even
downstreams when upgrading to a Kconfig with this change.

I've never heard of Kconfig as stable ABI. Christoph/Arnd, have you
heard of any cases where we want to keep it stable?

Of course not, otherwise we won't be able to do ANY cleanup in the kernel.

As far as I know we should change kconfig to keep it working properly,
eg by having correct menu structure and sane kconfig names.

Everyone who upgrades through source code and needs rebuild kernel
should be proficient enough to enable/disable kernel config.

Thanks
