> Ability to say that certain objects is far from both speaker and listener for example.

Non-native here. I don't quite follow. How about: "The object is far away from both of us.".

The concept is there, but maybe not as a single word. Sure, it might be convenient to be able to say "The object it broscht!", but it would just be syntactic sugar. Not a new concept.

Same for french coworker. Not a new concept.

"French person", "Frenchie", "Cheese eating surrender monkey"

Latter two might be SLIGHTLY inappropriate in a working environment.
