I very much lean towards (1). For conditional `noexcept`s, the compiler has to evaluate whether a function is `noexcept`, and if we can't find a reason this would be beneficial to users, I don't think we should make the compiler do that evaluation. For unconditional ones I don't have a strong opinion, but I have a feeling most of them will be `throws nothing` anyways.
