To me hasOwn() is as much a primitive as e.g. Object.keys(). The only odd thing about it is that it lives on Object.prototype rather than as a static method on Object. I don't see the inconsistency, unless you would also want to remove Object.keys() because it can be expressed in terms of gOPN + gOPD.
