AFAIK, the whole point of the spaceship changes was essentially to 
deliberately deprecate Boost.Operators; it should be no longer necessary 
to use any of it, because the compiler now does almost all of it for you.

(Also, can someone explain why x == y <==> y == x is controversial?  I 
have a hard time picturing a use case where you deliberately intend 
these to be non-commutative, outside of pathological library-fights.)
