It is actually used today. To see that, you only need to grep for use
this with CONFIG_IS_ENABLDE().

Of course it is never actually enabled, but that doesn't mean we can drop it.

The reason this works today is that CONFIG_IS_ENABLED() looks for
Kconfig options which are not actually in Kconfig. That is what I am
trying to change, since it is incompatible with separating out the
builds.
