Much of this is yet to be designed, but in general, our approach has been to lean towards a relatively layered system. That is to say, that at the lowest level, noms probably won't make a judgement about the trade-off you describe above, but rather provide primitives which allow layers above to more easily take opinionated positions. In the near-term we'll be paying attention to specific cases that arise, and we'd welcome the opportunity to learn more about those that you may encounter.
