Modularity is not only about reloading modules (although this can be
useful for developers in particular.) It's also about enabling many
features in a generic distribution kernel and each feature only gets
loaded/used on the hardware which needs it. This is why, as a
distribution kernel maintainer, I keep complaining when I see boolean
options which might easily be tristates.
