Try to set manual weather, set high humidity, heavy rain showers, temperature between 0°C and -20°C, dense overcast clouds and you will get very mild visual effect of icing after longer time, so YES they did corrected excessive visual depiction of icing BUT it is still not realistic at all.
You can fly with your Cessna 172 in icing environment all day long without stalling the aircraft, I’m surprised that I did not find any other thread about this topic.
