Danny, you're creation probably has more clout than even you realise. Maybe you could make an issue of this, perhaps get a few of your journo contacts involved. We all love to knock journos the way they sensationalise all things Aviation, but in this case, sensationalism might be what's needed.
I can just see tabloid headlines along the lines of "ICAO refuses to implement safety measures demanded by airline pilots group".
It's not as though the midair in Brazil is the first instance where this ultra accuracy has been the "final hole in the cheese" ensuring an accident occurs. I keep asking myself how many have to die before someone does something.
