The problem with that is that there are no kconfig maintainers:

  KCONFIG
  ...
  S:      Odd Fixes

The kconfig code is still a hard to maintain, scarcely documented mess. It 
took us almost a decade to rescue the NTP code from a similar obfuscation 
trap and make it maintainable. It had the same author as the original 
Kconfig code - and the Kconfig code is 10 times larger than the NTP code.

Thanks,
