My experience is this lasts about five minutes before someone starts using quibbles about the precise definition of "be awesome to each other" to suggest they should be allowed to be non-awesome to people and suffer no consequences for it. Sooner or later you have to actually set down some more specific guidelines and a mechanism for enforcing them.
I think a modern case around the Babylonian language confusion can be built around the fact that before you agreed on a common vocabulary, you may not at all be sure whether your exchange of ideas is actually being successful. A bit like talking about latitude and longitude coordinates, but later you find out the receiver was a flat earther.
