Airbubba :
Hmmm, this .1 nm offset must not have made it to the real world.
No it was refused in the end by ICAO for 2 reasons : mathematically on crossings with offset you increase the collision risk model (risk area is bigger ) and on principle/legal grounds that you cannot voluntary impose a decrease in navigation accuracy.
So yes with augmented GNSS coming in you will cross in opposite directions with the centre bar in the windscreens on top of one another .
Brings us back to making absolutely sure our barometric Altitude accuracy is perfect, especially in RVSM above FL400....
