It seems to me that these files have always been very neglected.
Perhaps a better solution would be to have 'make defconfig' generate them itself.
This would mean adding addition 'default' parameters to a ton of
existing options, and possibly also some 'if CONFIG_$ARCH' magic, but
that sounds like it would be more future-proof, and would also serve
as better documentation. (As a distro kernel maintainer, the number of
times I've hit undocumented "enable this on arch x, but leave disabled on arch y" is annoying).
