It may be that the feature is a glint model as discussed
http://forum.1cpublishing.eu/showthr...t=25931&page=5 . The white dots we now see may be the first stage, but without the data and coding needed to modulate the reflected light.
But I wouldn't call that a "major feature", rather a fairly minor programming effort. It may have a major effect on gameplay, though.
I'm certainly not aware that any other flight sim has a glint model. RoF certainly needs it, as it was quite a large factor in WWI. Maybe because of those flat, shiny doped wings, rather than curved aluminium ones.
Strangely, I don't recall WWII pilots mentioning it much in the accounts I have read. But you can imagine that a formation of, say, Heinkels at a large distance would remain at almost the same angle for quite a while and those big glass canopies would reflect at many angles.
