To get it into Boost, someone needs to contribute the tests and 
documentation and commit to maintaining it. :-)

That said, I'm not fond of this property of the cited implementation:

#

This implementation will mistakenly move from const lvalues.

    const unique_ptr<int> cp;
    unique_ptr<int> p(cp);  // should not compile
