Given that there is BOOST_NO_OPERATORS_IN_NAMESPACE, I don't think that 
the addition of the boost namespace to ADL was ever intended. I would 
rather see this fixed and the code that relies on this side effect 
broken (with the appropriate note in the release notes and the advice to 
use namespace qualification to resolve the problem).
