I am not sure for what reasons other packages would need to know the
Busybox options that are enabled.

Could be, yes. Not sure how that would work, though. We want to keep
this list of condition relatively short, and not encourage adding
millions of interactions between user space dependencies and kernel
options.

People using a custom kernel "know what they are doing", so I'm not too
interested in solving this particular use case.
