That's because what you're asking for is self-contradictory.  On
the one hand you want to be able to invoke the method on a const
reference.  On the other hand you want invoking the method on a
const reference to give a compile-time error.  Obviously the same
interface cannot do both, because either possibility necessarily
precludes the other.
