Loosing the ability to control the atmosphere within FlightGear would be a massive loss of functionality. We currently control atmosphere in several different ways like real weather based on METAR. The "local weather" project has just started to create a complex weather simulation system and I am (slowly but steadily) working on adding more live weather data, including aloft wind, temp and dewpoint for any point of this world. It would be a huge degression to be able to fly within ICAO standard atmosphere, only.
