What would such a potential optimization be like? Are you thinking of turning the 'platform_is(foo)' check into a compile-time choice, or are there more places where you can imagine an optimization? I'd like to understand better what you want to achieve there, maybe I can find a way to do that in the same series. =46or the 'at least one option selected' argument, I'm not sure how important that is, IMHO it falls into the same category as any other essential option that you can disable.
