I don't see why it shouldn't do better than required by the standard. It's quite normal for Boost components to extend the standard and provide superior solutions.
A few emails ago you were worried about wasted cycles.
Anyway, if existing functional/hash functions are not suitable for the task, we can add the bit mixing wrapper and recommend its usage with Boost.Unordered.
boost::hash should work well with std::unordered_map as it's defined in the standard and boost::unordered_map should work well with std::hash as it's defined in the standard. If that isn't the case then they're failures. These are generic components, they should just work without a wrapper or any such fuss.
