I experimented a bit more and it seems that these options are tied to the corresponding feature being enabled so they can be enabled in a fragment, unless the feature itself is enabled it will be ignored and disabled. So for disabled features/applets these options are moot. So as such, I think enabling them is a good thing as it will widen the ecompatibility for busibox systems.
