Yeah, I'm sure once distro configs are created we'll find quite a bit
similarity in them.  We could create Kconfig.distro that has all the
common options selected and then have the per distro Kconfig files
select that.  Sure we'd need to watch Kconfig.distro (or
Kconfig.min-distro) for changes, but I'd hope the distro maintainers
would sign up to maintain these things upstream and be keeping an eye
on it anyway.
